Objective

  • Kinetics Studies
    • Adsorption of CuSO4
  • DSC on glutaraldehyde and clay films

Description

  • It was directed to perform kinetics studies and adsorption of CuSO4 on glutaraldehyde (cross-linked) and Na-MT and any one of the exchange PVOH films (100 % CEC was selected).
  • DSC analysis was done on glutaraldehyde and clay films. The pieces were cut in to small fragments, and were allowed to sit out to get moistured.
  • For DSC analysis:
    • 0.00269 g of PVOH (MW=22,000g/mol)/glutaraldehyde(1 ml) films was placed in cell holder number A1
    • 0.00353 g of 1g PVOH (MW=22,000g/mol) with H3PO4 and maleic acid was placed in cell holder number B1
    • 0.0039 g of half gram PVOH (MW=100,000g/mol), HCl and succinic acid was placed in cell holder number C1
    • 0.00316 g of half gram PVOH (MW=100,000g/mol), H2O, maleic acid and H3PO4 was placed in cell holder D1
