Abstract: Abstract In this study, a novel flocculant called PDD was synthesized under ultraviolet irradiation using acrylamide (AM), methacryloyloxyethyl trimethylammonium chloride (DMC), and dimethyldiallylammonium chloride (DMDAAC) as monomers. The effects of monomer concentration, cationic degree, cationic… read more here.

DOI: 10.1016/j.jwpe.2019.100873
Abstract: Abstract Most of the mineral processing and hydrometallurgical plants consume large volumes of water. A portion of this water is recycled to the process while the remainder is lost. This necessitates optimization of dewatering systems… read more here.

DOI: 10.1111/wej.12536
Abstract: In this work, a new cationic flocculant, CMCTS‐g‐CPAM was synthesized by acrylamide (AM), methacryloyloxyethyltrimethylammonium chloride (DMC) and carboxymethyl chitosan (CMCTS) through UV initiated graft polymerization techniques. The structure of CMCTS‐g‐CPAM was analysed by infrared spectroscopy… read more here.
