The test sample (1 g) and deionized water (40 mL) were placed together in a 100 mL beaker, and stirred for 5 min with a magnetic stirrer to fully disperse the sample. The dispersed slurry was poured into a 100 mL settling cylinder. The upper layer (25 mL) of the settling cylinder was measured using a turbidity meter 2100AN (HACH, Loveland, CO, USA).
