Objective

• PVOH Glutaraldehyde Film Masses- Would use for Swelling studies

• Determine the maximum concentration of copper ions (Cu2+) in a 20 mg sulfate (SO42-) per liters of water.

Description

PVOH Glutaaraldehyde Film preparation fort swelling studies:

• 0.5 g PVOH, 8 ml millipore water, and 1 ml of glutaraldehyde.
• 0.4 g PVOH, 8 ml millipore water, and 1 ml of glutaraldehyde.

The films were prepared and stored for future experiments on swelling studies.

Determine the maximum Concentration of copper and sodium ions in 1 L of water with given 20 mg of sulfate (SO42-) ions

• (20 mgSO42-/1L H2O) * (1g SO42-/1000 mg) * ( 1mol SO42-/96g SO42-) * (1mol Cu+2/1mol SO42-) * (64 gCu/1mol Cu) = 13.3 mg Cu/L of water

• (20 mgSO42-/1L H2O) * (1g SO42-/1000 mg) * ( 1mol SO42-/96g SO42-) * (2mol Cu+2/1mol SO42-) * (23 g Na/1mol Na) = 9.58 mg Na/L of water

• 20ppm, 10ppm, 5 ppm, 2 ppm, and 0.2 ppm diluted solutions were prepared for CuSO4 and Na2SO4
