Abstract We developed a green adsorbent material from orange fruit peel for the removal of dyes from polluted water. The conversion of orange peels into green adsorbent was done by direct sunlight without using any chemical treatment. The adsorption study was carried with three different dyes namely, brilliant green, methyl violet, and solochrome black. Different concentrations of the dye solutions were prepared and evaluated for adsorption characteristics. The properties of the orange fruit peel and its interaction with dyes have been characterized by various analytical techniques. The UV-vis, Fourier transform infrared spectroscopy and visible color change results suggest that orange peels were effective toward removal of dyes from water. This method provides a simple, green and low-cost strategy for water purification.

Abstract Carbon quantum dots (CQDs) have great potential due to its advantageous characteristics of highly fluorescent nature and good stability. In this study, we aimed to develop a simple and efficient method for the green synthesis of fluorescent CQDs from sugarcane bagasse, a renewable and sustainable resource. The process involves the top down approach of chemical oxidation followed by exfoliation of sugarcane carbon. The synthesized CQDs was characterized by UV–vis absorption spectroscopy,...

Abstract This work reports the recycling of waste rubber tires (WRT) to produce a carbonaceous material as adsorbent of an environmental value. The produced material was activated by thermal–chemical process. The WRT-derived carbonaceous adsorbent (CA) was characterized by means of scanning electron microscope, energy-dispersive X-ray spectroscopy and infrared and Raman spectroscopic techniques. The developed CA was tested and evaluated as potential adsorbent for methyl orange (MO) removal. A se...

As an agricultural waste available in large quantity in China, Orange peel was utilized as low-cost adsorbent to remove furadan from aqueous solution by adsorption. Pseudo-first-order, second-order models and intraparticle diffusion model were applied to analyze experimental data and thus elucidated the kinetic adsorption process. The high values of correlation coefficients showed the data conformed well to the pseudo-first-order rate kinetic model over the initial stage of the adsorption proces...

Abstract An iron terephthalate (MOF-235), one of the metal-organic frameworks (MOFs), has been used for the removal of harmful dyes (anionic dye methyl orange (MO) and cationic dye methylene blue (MB)) from contaminated water via adsorption. The adsorption capacities of MOF-235 are much higher than those of an activated carbon. The performance of MOF-235 having high adsorption capacity is remarkable because the MOF-235 does not adsorb nitrogen at liquid nitrogen temperature. Based on this study,...

The adsorption of methyl orange and methyl violet from aqueous solutions by Phragmites australis activated carbon (PAAC) was studied in a batch adsorption system. The adsorption studies include both equilibrium adsorption isotherms and kinetics. Several isotherm models were investigated and the adsorption isotherm data were best represented by the Temkin isotherms. The kinetic data were well described by the pseudo-second-order kinetic model. The mechanism of the adsorption process was determine...

The citrus-processing industry generates in the Mediterranean area huge amounts of orange peel as a byproduct from the industrial extraction of citrus juices. To reduce its environmental impact as well as to provide an extra profit, this residue was investigated in this study as an alternative substrate for the fermentative production of citric acid. Orange peel contained 16.9% soluble sugars, 9.21% cellulose, 10.5% hemicellulose, and 42.5% pectin as the most important components. To get solutio...

Abstract De-Oiled Soya a waste of Soya oil industries and Bottom Ash a waste of thermal power plants have been used as effective adsorbent for recovery and removal of hazardous dye Methyl Orange from wastewater. During the studies effects of amount of dye and adsorbents, pH, sieve sizes, column studies etc. have been carried out. Adsorption of the dye over both the adsorbents has been monitored through Langmuir and Freundlich adsorption isotherm models and feasibility of the process is predicted...

In the present study adsorption of Cr(VI) from aqueous solutions onto different agricultural wastes, viz., sugarcane bagasse, maize corn cob and Jatropha oil cake under various experimental conditions has been studied. Effects of adsorbent dosage, Cr(VI) concentration, pH and contact time on the adsorption of hexavalent chromium were investigated. The concentration of chromium in the test solution was determined spectrophotometrically. FT-IR spectra of the adsorbents (before use and after exhaus...

Abstract The adsorption of Cr(VI) ions from aqueous solutions onto waste of tea factory in fixed beds was investigated. Experiments were carried out as a function of liquid flow rate, initial feed of Cr(VI) concentration, particle size, feed solution pH and bed depth. The bed capacities were found to increase with decreasing flow rate and particle size. The maximum bed capacities for the tested flow rates were found to be 55.65, 40.41 and 33.71 mg g - 1 at 5, 10 and 20 ml min - 1 , respectively....

Adsorption techniques are widely used to remove certain classes of pollutants from waters, especially those that are not easily biodegradable. Dyes represent one of the problematic groups. Currently, a combination of biological treatment and adsorption on activated carbon is becoming more common for removal of dyes from wastewater. Although commercial activated carbon is a preferred sorbent for color removal, its widespread use is restricted due to high cost. As such, alternative non-conventiona...

Efficient separation and removal is necessary in applications ranging from environmental remediation to the food sector. A well-designed adsorption system should meet the demands for high efficiency in a cost and time effective manner. In wastewater treatment, the ideal chemical feedstock used to synthesize the adsorbents should themselves been environmentally friendly (i.e. non-toxic) to avoid subsequent environmental issues. Nanocellulose, made of the most abundant organic biopolymer on earth,...

Abstract The destination of agro-industrial waste becomes an increasing problem especially for agricultural countries. In this work, physicochemical modifications were performed in agro-industrial residues of sugarcane and cassava, aiming to describe their potential application as biosorbents. All raw materials were treated with NaOH 0.10 mol L−1 and the ashes were produced by carbonization and calcining at 600 °C for 6 h. The biosorbents were characterized in terms of chemical composition, pHzp...

Abstract Lemongrass leaf based activated carbon (LGLAC) was prepared using physico-chemical methods for methyl red (MR) dye removal from aqueous solutions. The surface chemistry of LGLAC before adsorption revealed the presence of different functional groups: O-H, C-H, C=O, CH3, C=C, N-O, C-O and C-N which were shifted after methyl red dye adsorption. Brunauer-Emmett-Teller surface and mesopore areas are 836.04 m2/g and 598.6 04 m2/g, whereas, the average pore diameter and total pore volume of LG...
