Chitosan in acid was polycationic and can react with negative charges like tripolyphosphate. Tripolyphosphate was a crosslinking agent with low toxicity. This study was to review the ability of crosslinked chitosan-tripolyphosphate (Cs–TPP) in reducing the color levels of methyl orange. Synthesizing Cs–TPP was conducted by reacting chitosan solution with acid tripolyphosphate. The Cs–TPP was characterized using FTIR and determined for its molecular mass. The adsorption study of methyl orange was conducted at various pH, contact times, and the determination of adsorption isotherm. The spectra IR analysis showed that there was adsorption of –PO groups in the Cs–TPP in the area of 1026 cm−1. The molecular mass of Cs–TPP was 345.24 x 103 g/mol. Cs–TPP optimally absorb methyl orange at pH 7 and a contact time of 120 minutes, with presence removal of 47.36%, and followed the Freundlich adsorption isotherm pattern.
