摘要：

Sulfonated phthalic magnesium salt (SPMS) was used in the leather deliming process. The deliming properties of SPMS was determined with the indicators such as the change of pH, content of NH4-N, COD of deliming float, deliming speed, etc. The results show that SPMS has a mild deliming ability, excellent buffering and calcium removal performance; the total nitrogen content of deliming float is 3.4% of the conventional deliming process. Comprehensive performance of deliming is well and the delimed crust has a fine, smooth grain. It can be used as non-ammonium deliming agent in the clean leather manufacture, and it will benefits for the energy saving and emission reduction of leather industry.
