The experimental results were followed:(1) LY402 could degrade chlordane in an aerobic environment. The percent of chlordane degradation at 1.0 mg /L was more than 94% after 4 days at 30℃. When exposed to a concentration as high as 10.0 mg/L, LY402 could still degrade 61% of chlordane. There was no obvious difference between cis-chlordane and trans-chlordane in the mixture on biotransformation rate.

The results show that the shrinkage temperature of the leather tanned with QUIMITAN ABC is 101.4℃, and the physical-mechanical properties of QUIMITAN ABC tanning leather are better than that of chrome powder tanning leather; the content of Cr2O3 (0.4142 g/L) in the float of QUIMITAN ABC tanning is lower than that of the content of Cr2O3 (1.9481 g/L) chrome powder tanning, it's clear that QUIMITAN ABC tanning is good for Cleaner production; under the same content of chromic oxide, the physical properties of retanning leather with QUIMITAN ABC are better than that of retanning leather with chrome containing sytan and chrome powder, such as thichkening, flexibility, physical-mechanical properties.

结果表明：QUIMITAN ABC主鞣后的坯革的收缩温度为101.4℃，且其坯革物理力学性能高于用6%的铬粉主鞣后的坯革；QUIMITAN ABC主鞣后的废液Cr2O3含量(0.4142 g/L)明显低于用6%的铬粉主鞣后废液Cr2O3含量(1.9481 g/L)，用QUIMITAN ABC主鞣有益于清洁化生产；在Cr2O3含量相同的情况下，用QUIMITAN ABC复鞣的坯革在增厚率、柔软度、物理力学性能等方面都要好于含铬鞣剂及铬粉复鞣的坯革。
