按照国标法用石墨炉原子化吸收光谱法测定饮水中铅、镉、镍、钼、钡、银等金属元素,都是采用将基体改进剂先加入水样和标准系列中再上机测定。由于所加基体改进剂不同,每测定一个元素都必须重新取水样,重新配制标准系列。国标法对上述元素的测定采用的是逐一分别测定。本文根据加基体改进剂的有关方法及现有仪器设备的特点,采用 Determination of lead, cadmium, nickel, molybdenum, barium, silver and other metal elements in drinking water by graphite furnace atomic absorption spectrometry according to the national standard method are all carried out by adding the matrix improver first into the water sample and the standard series and then measuring with the machine. Due to the different matrix modifiers added, each element must be re-taken a sample of water, re-preparation of the standard series. National standard method for the determination of the above elements are used one by one were measured. This article based on the method of adding matrix improver and the characteristics of the existing equipment, use
