Preliminary research on Cr(IV) removal in a liquid waste using guava leaves (Psidium Guajava) as a bio-sorbent has been done. The experiments were conducted in a stirred batch reactor. The effect of temperature on efficiency and absorption capacity has been studied. Both the efficiency and absorptioncapacity are directly proportional to the temperature under the current experimental conditions. The results showed that optimum absorption capacity and absorption efficiency of Cr(VI) use of guava leaves obtained at stirring time 30 minutes.
