Preparation of stock polymer solution. Stock polymer solutions were prepared at a concentration of 0.01% for spiking in the samples. The polymers were prepared using a jar test apparatus (Phipps and Bird, USA) by mixing 0.1 g polymer in 1000 mL of deionized water at a speed of 220 rpm for 5 min, followed by mixing at a speed of 125 rpm for 55 min.
