==Objective==

Objective 1) Prepare 3 PVOH Films (plain MW 22,000, glutaraldehyde cross-linked, and porphyrine dihydrogen chloride cross-linked.

Objective 2) Atomic Absorption Spectroscopy for all Cu standards.

==Description==

* 3 PVOH films were prepared: 0.5 g MW of 22,000, 1 ml glutaraldehyde, and 1 ml of porphrine dihydrogen chloride.
* AAS studies for all the Cu standards: NaMT- concentration of 1.25 g/500 ml, for 1min, 5 min and 10 mins standards, 50 % CEC exchange-concentration of 1.25 g/500 ml, for 1 min, 5 min and 10 mins standards, 100% CEC exchange, for 1 min, 5 min and 10 mins standards, and Fe3O4-concentration of 1.25 g/500 ml, for 1 min, 5 min and 10 mins standards.
