Backgrounds and Aims: The purpose of this study was to examine the effects of potassium, sodium and zinc metal ions on ammonium sulfate fraction of acid phosphatase activity of orange fruit. Materials and Methods: Acid phosphatase was extracted and purified from orange fruit and then various samples as well as a control sample were prepared in vitro. In addition to substrates, ions of potass...

Adsorption and water treatment of Ca (II) and Mg (II) hardness were investigated via adsorption of metal ions onto commercial polyacrylic acid hydrogel beads as a novel sorbent for metal ions (Ca2+, Mg2+) removal and water treatment. Batch equilibrium technique was carried out under the influence of solution pH, contact time, sorbent dosage, initial metal concentration and...
