应用9-(2-羟基乙氧甲基)鸟嘌呤试剂紫外分光光度法测定硼
UV Spectrophotometric Determination of Boron with the Reagent 9-(2-Hydroxy-ethoxy-methyl)-guanine
摘 要
提出了用9-(2-羟基乙氧甲基)鸟嘌呤(ACV)作试剂的紫外分光光度法测定硼的方法.研究表明,ACV与硼酸在pH 12.0的缓冲溶液中形成的反应产物,其最大吸收波长为289 nm,吸光度与硼的质量浓度在0.31~31.2 mg·L-1范围内呈线性关系.检出限(3s/k)为0.27 mg·L-1.方法直接用于冰硼含片和尿样中硼的测定,并以此样品为基体用标准加入法做回收试验,测得回收率在99%以上.

Abstract
9-(2-Hydroxyethoxy-methyl)-guanine (Acyclovir,ACV) was used as reagent in the UV-spectrophotometric determination of boron.In a buffer medium of NaOH-KCl solution at pH 12.0,a coordination complex was formed between borate and ACV,having its absorption maximum at the wavelength of 289 nm.Linearity range was kept from 0.31 to 31.2 mg·L-1 for boron.Detection limit (3s/k) found was 0.27 mg·L-1.The proposed method was used in the analysis of drug samples and urine samples for their boron contents.Tests for recovery were made by the standard addition method using these samples as matrixes,values of average recovery found were over 99%.
