Facile synthesis of novel pH-sensitive grafted guar gum for effective removal of mercury (II) ions from aqueous solution

Acrylamide and acrylic acid was grafted on guar gum via microwave-assisted technique without using any initiator to prepare a new pH-sensitive adsorbent for mercury (II) ions removal from aqueous solution. The fabricated adsorbent [GG-g-poly(Am-co-AA)] was characterized via SEM, FT-IR, XRD, and TGA analytical techniques to confirm the grafting of acrylamide and acrylic acid on guar gum. The influence of numerous procedure parameters like...
