A graphite furnace atomic absorption spectroscopy examination has been used to measure trace amount of Sb, Pb, Cd released from enamel appliance and the optimum measuring conditions, such as ash temperature, atomization temperature and time have been obtained in this work. The results show that this method has many advantages-promptitude, convenierce, high sensitivity and slight interference. The sensitivities of Sb, Pb, Cd in this method are 3.3×10-11, 1.0×10-11, 1.2×10-12g/1 % absorption respectively....

A graphite furnace atomic absorption spectroscopy examination has been used to measure trace amount of Sb, Pb, Cd released from enamel appliance and the optimum measuring conditions, such as ash temperature, atomization temperature and time have been obtained in this work. The results show that this method has many advantages-promptitude, convenierce, high sensitivity and slight interference. The sensitivities of Sb, Pb, Cd in this method are 3.3×10-11, 1.0×10-11, 1.2×10-12g/1 % absorption respectively. Their rates of recovery are 96~106%, 98~110%, 98~108% respectively. The relative standard deviations for the solution containing 10ppb Sb2O3, 8ppb PbO, and 2ppb CdO are 10.6%. 4.6% and 3.1% respectively.

本文介绍了用石墨炉原子吸收光谱法直接测定搪瓷餐具浸出液中痕量元素锑、铅、镉,并对这三种元素的灰化温度、原子化温度和原子化时间进行了选择试验。结果表明,本方法其有快速、简便、灵敏度高、干扰少等优点。采用本方法测定锑、铅、镉的灵敏度分别为3.3×10~(-11)、1.0×10~(-11)、1.2×10~(-12)克/1%吸收;回收率分别为96~106%、98~110%、98~108%;对于10ppb锑、8ppb铅、2ppb镉的溶液,其相对标准偏差分别为10.6%、4.6%和3.1%。
