Most Zn hydrometallurgy factories adopt Cu2SO4 as a dechlorination reagent from zinc solution recently, thus much CuCl residue was produced. The present process of treating this residue is washing CuCl residue with water or sodium carbonate solution, which would bring a lot of trouble for water treatment and waste discharge. In this study, a method of roasting the residue with microwave energy is...
In this work, we report the synthesis, antifungal and antioxidant activity of a novel chitosan (CS) derivative, PTACS, derived from chloracetyl chitosan (CACS), 4-pyridinecarboxaldehyde and thiosemicarbazide. The result indicated that both the antifungal activity and the antioxidant property of PTACS are better than CS.
