acid, Scheme 1) as a new chromogenic anion receptor, can selectively and efficiently be applied for detection of AcO− over wide range of anions such as BzO−, F−, Cl−, Br−, OH−, I−, NO3−, HSO4−, CN− and CO32− in mixed DMSO/H2O media. Increasing the amount of H2O up to 50% (v/v) caused a dramatic development in selectivity of AcO−. The developed BPR enabled the determination of acetate in the linear concentration
溴邻苯三酚红BPR(2-(2,7-dibromo-4,5,6-trihydroxy-3-oxo-3H-xanthen-9-yl)苯磺酸,方案1)作为新的生色阴离子受体,可以选择性地且有效地应用于检测ACO的-在宽的范围内的阴离子,如BZO的-,F - ,氯- ,溴-,OH - ,我- ,不3-, HSO4-,CN -和一氧化碳32个-在DMSO / H 2 O混合介质中。增加H的量2 O最多至50%(V / V)中的ACO选择性引起的显着发展- 。所开发的BPR能够测定线性浓度范围为19.0–42.0μM(1.12–24.8μgmL -1)中的乙酸盐,检出限为2.5μM(0.147μgmL -1)和相对标准偏差(RSD,C = 19.4μM,n = 5)小于1%。这样就可以设计和开发可重复使用的光学受体,以监测醋样品中的痕量乙酸根离子以及与制造商所提及的值一致的值。
