MG Adsorption Prior adsorption observations all solutions colorless require more concentrated solutions & less clay note that 10mg of clay = 0.0092 mequiv exchangeable sites = 10mL 0.92mM dye = 10mL 426ppm dye Prepared new Stock Solutions 800ppm was too concentrated (undissolved solid) 80ppm was mostly dissolved Moisture Absorption of PVOH dried previously cut PVOH after 2 d at 90°C, mass = 0.10722 g dry mass = 0.2888(wet weight) placed back in water to test rehydration ability MG Adsorption isotherm tested NaMT & 10%NaMT/PVOH in 80ppm MG only same method as 8/1
