The prepared raw fish bone was used as the effective sorbent for the removal of organic dyes. The waste fish bone was collected from the local market in Banmaw, Kachin State. Physicochemical properties of fish bone such as moisture, pH, bulk density and specific surface area were determined by recommended methods. Fish bone sample was characterized by modern techniques such as EDXRF and SEM analyses. Sorption studies of fish bone sample were carried out by spectrophotometric method. Two model dyes Congo red as acid dye and Malachite green as basic dye were used in sorption experiments. The effect of sorption parameters such as initial concentration, contact time and adsorbent dosage on the removal of specified colored dye was investigated. The maximum removal percent of Congo red was found to be 62.33% at the specified conditions such as initial dye concentration (50mgL-1), dosage (0.1g/20mL), and contact time (90min). In the case of Malachite green as sorbate, the maximum removal percent was detected as 76.04% under the conditions which were the same as sorbate Congo red.
