PENYERAPAN ION LOGAM KROM (III) PADA TANAH GAMBUT

Abstract

Absorption of chromium metal ions (III) by peat (0.5 g) obtained on peat soilparticle size 150 μm, pH 5 metal ions, metal ion concentration of 20 ppm. Themaximum absorption capacity of the peat soils of the ion chromium ion (III) 0.38 m/l. The efficiency of absorption of chromium metal ions (III) in soil peat 50.56%,while the efficiency of absorption of chromium metal ions (III) on humic acidstandard of 67.31%. Peat applications as metal ion absorption of chromium (III) inwaste water by 91.39%, whereas the absorption efficiency of metal ion chromium(III) in waste water with humic acid standard of 99.10%.
