ObjectiveTo make a film containing PVOH/glutaraldehyde, prepare 100% and 50% CEC clay with HdPh3P+, and to prepare Na-MT coated with iron oxide.
DescriptionPVOH/Glutaraldehyde Film
Data100% CEC Clay Calculations (0.92 meqv/g surfactant)·(2 g clay)·(1 eqv/1000 meqv)·(1 mol surfactant/1 eqv)·(567.62 g/mol surfactant) = 1.06 g surfactant
5 mol/L · 39.97 g/mol = 199.985 g/L · 0.05 L = 9.99 g NaOH to make a 50 mL stock solution
