Glutaraldehyde Cross-linking, 100% Exchange Na-MT (2g), 50% Exchange (make 2 g) and γ-Fe3O4 Coated Na-MT( for making a magnetic Absorbent-2g). DescriptionPart A:
Part B: The standard preparations (1-1/50 of the 20 ppm stocks standards were made in the amount of 5 diluted solution. Part C:
Expt 1) 1 min Expt 2) 5 mins Expt3) 10 mins Note: The clean, dry filter flask was used. Dry filter paper, Number 41, was used. When pouring, the solution was transferred to the center of the paper, same filtrate, (20 ml vials) in a slow movement. Part D: part C was repeated by using 100 % CEC surfactant clay. Part E:
Part F: Part E was repeated by using 100% CEC surfactant clay. Part G:
