摘　　要：运用正交设计方法研究了不同有机配体对锆-铝-钛多金属鞣液稳定性的影响。考察了配体种类,物质量比,放置条件,熟化时间和pH值对锆-铝-钛多金属鞣液沉淀pH值的影响,并对优化条件下锆-铝-钛多金属鞣液的稳定性性能进行表征。实验结果表明:配体为柠檬酸,金属离子总量与配体的物质量比为1∶0.16,条件为室温,熟化时间为24 h,pH值为1.5的锆-铝-钛多金属鞣液稳定性最佳。Using the method of orthogonal experiment study the effect of the different organic ligands on the stability of the Zr-Al-Ti multi-metal complex solutions.Inspected to the ligand amount,molar ratio,disposition condition,curing time and pH,which affect the pH value of precipitates of the Zr-Al-Ti multi-metal complex solutions,and under the optimal condition,the stability of the Zr-Al-Ti multi-metal complex solutions was characterized.The result showed that stability of Zr-Al-Ti multi-metal complex solutions was best when the ligand was the citric acid,molar ratio was 1∶0.16,the condition was the room temperature,curing time was 24 h,pH was 1.5.
