摘要
采用循环伏安法测定了以铁氰化钾为水相的司盘80/吐温80/正丁醇/异辛烷复配反相微乳液的扩散系数,并结合黏度测试,建立了推算复配反相微乳液液滴大小的新方法。测试结果表明,该复配反相微乳体系在工作电极上的电化学行为是扩散控制的可逆过程;推算结果表明,该复配反相微乳体系液滴都在纳米范围内,符合理论液滴大小,且液滴大小随含水量的变化规律可理论解释,证明了采用循环伏安法测定复配反相微乳液液滴大小的可行性。
Diffusion coefficients of Span 80/Tween 80/butanol/isooctane compound reverse microemulsion with potassium ferrieyanide as water phase are measured by cyclic voltammetry, and a new method of calculating drop sizes of compound reverse mieroemulsion is established combined with viscosity test. The test results show that the electrochemical behavior of compound reverse microemulsion system in the working electrode is diffusion-controlled reversible process. The calculating results show that the drop sizes of compound reverse microemulsion are in the nanometer scale and consistent with the theoretical value. The variation of water content with drop size could be explained theoretically, that could prove the feasibility of determination of drop size of compound reverse microemulsion using cyclic voltammetry.
