In a batch system, the Cu(II) preconcentration parameters were optimized using chitosan crosslinkeddialdehyde carboxymethyl cellulose (CS-DCMC). The experiment started with carboxymethyl cellulose oxidation by periodate to form DCMC. The CS-DCMC adsorbent was then prepared with a mass ratio of CS-DCMC = 1:1. The adsorbent is characterized by FTIR for functional group analysis and SEM-EDX for morphological analysis and the percentage of elements in CS-DCMC adsorbent. In the optimization of preconcentration parameters, the optimal adsorption, desorption, and enrichment factors were obtained at pH 4, the adsorbent mass of 90 mg, adsorption time of 95 min, Cu(II) concentrations of 7 mgL-1, and Na2EDTA 1 M. The application of CS-DCMC on wastewater containing Cu(II) under optimal conditions gave good results. Wastewater containing Cu(II) 0.1 mgL-1, can be concentrated to 0.53 mgL-1, with an enrichment factor of 5.26 times, 0.2 mgL-1, Cu(II) can be concentrated to 1.08 mgL-1, with an enrichment factor of 5.40 times, and 0.3 mgL-1, Cu(II) can be concentrated to 1.68 mgL-1, with an enrichment factor of 5.59 times. The enrichment factor obtained is almost close to the theoretical enrichment factor of 6 times.
