The effect of initial concentration of Cr(VI) on adsorption to black water of Gambut, District of Banjar, South Borneo has been investigated, as well as interaction betwen Cr(VI) species and functional black water organic fraction. The initial work was optimization of Cr(VI) determinition using UV-Visible Spectrophotometry with diphenylcarbacide as complexing agent and preparation of black water using mixture of 2% HCl and 5% HF with HCl-HF ratio of 1 : 1 (v/v). The quantity of Cr(VI) species adsorbed on black water was calculated by determining the amount of Cr(VI) species in solution before and after interaction. The functional groups in interaction between Cr(VI) species and black water organic fraction was studied qualitatively using infrared
