Chemically Treated Rice Husk Blends as Green Desiccant Materials for Industrial Application

The use of rice husks (RHs), treated RHs, and blends thereof as desiccants was studied. Bare RHs, treated RHs, and blends were characterized, and their water absorbances compared. Acid‐treated RHs showed better moisture absorbance than alkali‐treated RHs and hence were used to prepare blends. Moisture absorption of RH materials and silica gel were compared. Blends with a higher content of acid‐treated RHs showed higher water and moisture...
