    Phenolic compounds are organic pollutants that are toxic and carcinogenic.The presence of phenol in the environment can be adverse to human and the environmental system. One method that is effective to reduce the phenol is adsorption. In this study, the adsorption of phenol in aqueous solution using Ca-bentonite/chitosan composite was investigated. Chitosan is the deacetylation product of chitin from shrimp waste. Characterization of Ca- bentonite/chitosan composite was done by using Fourier Transform Infrared (FTIR) and Scanning Electron Microscopy-Energy Dispersive X Ray Spectroscopy (SEM-EDX). Batch adsorption studies were performed to evaluate the effects of some parameters such as initial concentration of phenol, composite weight, pH and contact time. The results showed that FTIR spectra of Ca-bentonite/chitosan composite presented the characteristic of peak of Ca- bentonite and chitosan that confirmed the successful synthesis of composite. The SEM-EDX characterization results showed Ca-bentonite surface coverage by chitosan and the presence of carbon and nitrogen elements in Ca- bentonite/chitosan composite indicated that chitosan had bonded with bentonite. The optimum condition of adsorption of Ca-bentonite/chitosan to phenol was obtained at 125 mg.L-1 of concentration in which the weight of composite was 1.0 g, the pH of solution was 7, the contact time was 30 minutes, and the capacity of adsorption was 12.496 mg.g-1
