Abstract
ABSTRACT Filter paper (100% cellulose) was treated with either a 25% solution of polyacrylic acid (PAA) or poly (4-vinyl) pyridine powder (PVP). The dried paper was held under vacuum, treated with a 5% solution of PAA, heated and washed. The treated paper was then exposed to Ar-plasma to crosslink the PAA on the surface of the paper. The paper was dried, washed again and dried again. The treated paper was then tested for its ability to remove Cu++ from solution at different concentrations and different pH conditions. The PAA/Ar-plasma removed 350 mg Cu++ per gram of PAA while the PVP/Ar-plasma removed 19 mg Cu++ per gram of PVP. Untreated paper removed very little Cu++ from solution.
