摘要: This paper presents the result of dyeing solution coagulation with use ferrous ammonium sulfate hexahydrate (FAS). The examined contains two reactive dyes: Black 5 and Blue 19. It has been shown that efficiency dye removal depends on type dye, dosage initial pH. Our showed increase pH up to 12 enhanced color efficiency; FAS dose was determined 280 ml (Black 5) 180 mg/l (Blue 19) at slow mixing time 15 min, agitation speed 60 rpm, concentration should be 50 100 mg/L for 19, respectively.
