非离子表面活性剂OP-10浊点的测定及其影响因素的研究

摘要

This paper determines the cloud point of nonionic surfactant OP--10, and studies the variation of the cloud point when adding different inorganic material and controlling them at various pH value. The re- sults show that various anions decrease cloud point in 1 %OP--10 as following:OH〉CL_〉NO3_. The de- crease of cloud point in 1 %OP--10 with addition buffer solution is more than that of cloud point in 1% OP --10 with addition phosphoric acid at same pH value.%测定了非离子表面活性剂0P-10的浊点，并研究了添加不同无机物以及控制在不同酸性pH值时OP-10的浊点的变化规律，实验结果表明：阴离子降低0P-10的浊点遵循OH-〉Cl〉NO3-；阳离子对浊点影响小于阴离子；在相同pH值时，添加缓冲溶液的浊点下降幅度大于添加磷酸溶液。
