以含水量85％的O/W型SDS/正丁醇/正庚烷/水微乳液为介质进行Zn(Ⅱ)-PAN微量测定,ε=5.15×10~4L·mol~(-1)·cm~(-1),与以相同含水量的SDS胶束体系(ε=3.51×10~4L·mol~(-1)·cm~(-1)比较,测定灵敏度显著增加,某些实验条件改善。
Zn (Ⅱ) -PAN was measured with O / W SDS / n-butanol / n-heptane / water microemulsion containing 85% water. Ε = 5.15 × 10 -4 L · mol -1 cm ~ (-1). Compared with the SDS micellar system (ε = 3.51 × 10 ~ 4L · mol ~ (-1) · cm ~ (-1)) with the same water content, the sensitivity was significantly increased. Under certain experimental conditions improve.
