【摘要】 利用自制一组流动比色装置,应用到双光束检测器中,提出一种新的流动注射微分光度测试技术。一次进样,同时获得两峰两谷四个微分响应信号(△A1、△A2、△A3和△A4)。研究了在乙酸—乙酸钠介质中,Al-EGTA-PR-CPB四元体系显色反应的适宜条件。进样频率120次/时,若采用加和技术方法的灵敏度为普通的4.7倍,可用于环境水中微量铝的测定。更多还原

【Abstract】 Using a suit of flow compare colour packaging of own that is applied to test ware with double beams.Then put forward a new differential spectrophometric tes technology with flow injecting.Entering the sample once can achieve two peaks and two volleies four differential respond signal at the same time(△A1、△A2、△A3、△A4).This suit can be used to research Al-EGTA-PR-CPB’s suitable condition of showing colour reaction with for units in the condition of HAC-NaAc.Its entering sample frequency is 120 times per hour.If using add together technology method,sensitivity is 4.7 times than the common method.This suit can be used in measuring the trace aluminium in the environmental water.更多还原
