Abstract

Tanning industry potentially produces waste containing heavy metals chromium (Cr) is harmfull to the environment. One of the method to decrease the Cr in liquid waste is using soil as adsorbent. Soil capacity to adsorb of heavy metal is determined by clay content, soil moisture, redox potential, pH, organic matter content and CEC. The research aim to determine the soil capacity of Vertisols, Oxisols, Entisols, and Andisols to adsorb Cr in liquid warte from tanning industry. The experiment conducted in this research was to flow and saturate the liquid waste into soil column four soil samples. The adsorption capacity of each soil type was calculated by comaring Cr content in the soil with in the filtrate. The results showed that the soil is a good Cr adsorbent and each soil type has different abilities in the adsorption of heavy metals Cr. At first saturation the soil is able to adsorb Cr about 99,92%, the second satoration at 99,64%, and the third saturation of the soil is able to adsorb Cr 97,17%. The adsorption capacity of Entisols and Oxisols was 0,174 mg/g. Andisols has an adsorption capacity of 0,175 mg/g, and Vertisols has adsoprtion capacity of 0,177 mg/g
