- Pollution caused by Cr(VI) metal is harmful because it is toxic and carcinogenic. Utilization of cow bone waste is considered not optimal. One of the utilization is as an adsorbent of Cr(VI) metal. This research aims to determine the adsorption capacity by bone waste bone adsorbent in lowered Cr(VI) metal, and to determine the adsorption isotherm model. Cow bone waste carbonized with furnace at a temperature of 800°C for 1 hour until it became charcoal. A size of 100 mesh and Na2CO3 5% activator were used and soak for 24 hours. In this research, shaker and waste simulation were used in batch method. Variations used include variation of mass of adsorbent (gram) : 0,4 ; 0.6 ; 0.8 ; 1 ; 1,2 and stirring time (minutes) : 15, 30, 60, 90, 120. The analyzed parameters were Cr(VI) metal concentrations. The research result showed that percent removal in optimum condition of adsorption adsorbent using cow bone waste at mass of 1,2 gram with stirring time 90 minutes was 66,92% for the non-activated adsorbent and 82,20% of percent removal at mass 1,2 gram with stirring time 120 minutes for the activated adsorbent. The adsorption isotherm followed the Freundlich model with the value R2 = 0,9968 for the non-activated adsorbent and the value of R2 = 0,9909 for the activated adsorbent.
