Chitosan - kaolinite beads. Preparation of chitosan dissolved in acetic acid to a solution of concentrated percent weight by volume 3.0 and 5.0, with kaolinite are the materials used 0.3, 0.5, and 1.0 grams of sodium tri-poly-phosphate concentrations percent by weight. v 5.0 and sodium hydroxide concentration of 10.0 percent weight by volume is a crosslinking agent. The experiment absorbent solution chromium (VI) concentrations of 5, 10 and 20 milligrams per liter. At room temperature in acid at a pH of 4.0, results showed that the highest efficiency in the removal of chromium (VI) ions using chitosan - kaolinite beads with the percentage 96.23 of nitrogen on the amino groups of chi. Master San act as electron donors to Cr (VI) ions is complex. The adsorption isotherm is ...... Restoration chitosan - kaolinite beads for reuse. 0.1 using hydrochloric acid normally found that chitosan - kaolinite bead crosslinked with sodium tri poly phosphate desorption values equal ..... The chitosan - kaolinite bead crosslinked with sodium hydroxide beads melt with hydrochloric acid solution.
