Flocculation abilities of industrial cationic starches (in English)
Polimery 2011, No 3, 244
Flocculation abilities of five industrial cationic starches were investigated. The research was performed on suspensions of kaolin, bentonite and natural clay. Time dependence of turbidity was determined using the nephelometric method. It was found that modified cationic starches are quite good flocculants for aluminosilicate suspensions, especially for natural clay. The highest flocculation efficiency showed the potato starch BORCET SZ 2000 characterized with the highest substitution degree.
