Abstract:In this study, dextran (DEX) cryogels were prepared using 50% divinyl sulfone (DVS) crosslinker based on the repeating unit of DEX, under cryogenic conditions via cryogellation technique. It was shown that DEX cryogels can be used as column fillers to remove toxic substances such as organic dye, methylene blue (MB), pesticide, and paraquat (PQ) which are harmful to the environment and human health. The maximum absorption capacity of 15 mg DEX cryogels was determined as 10.69±0.14 mg/g using 5 mL of 100 ppm MB … Show more
