    The nature of catalase, immobilized in sodium carboxymethyl cellulose (CMC) and poly(n,n-dimethylaminoethyl methacrylate)(PDM), were primarily studied. The results showed that the CMC/PDM capsules, which were made by 2.0% of mass concentration of CMC and 25% of mass concentration of PDM, were the smoothest, the hardest, and the most effective. The optimum pH and temperature were 7.0 and 40°C respectively for immobilized catalase, while the optimum pH and temperature were 7.0 and 35°C respectively for dissociative sucrase. So, the range of applying of pH of immobilized catalase was more extensive. The immobilized catalase has 66% activity when it was stored 16d at 35°C and has 17% activity when it was repeated used five times at 40°C.
