【摘要】 本文主要研究了利用巯基棉在pH5—6.5的微酸性条件下,富集废水中痕量镓、镉、铅等元素的化学光谱测定。进行了一系列化学干扰及光谱条件等试验。用本法测定了废水样品,获得了较满意的结果。该法具有简便、快速及灵敏的特点。更多还原

【Abstract】 In this paper, a chemical spectrometry determination of trace amounts of Ga, Cd, Pb elements in waste water enriched by sulfhydryl cotton under weakly acidic condition, pH5-6.5, has been investigated.The chemical and spectral conditions have been selected and the interference has been examined by means of experiments. Making use of this method, we have determined waste water samples with satisfactory results. This method displays the chracteristics of simplicity, quickness and sensitivity.更多还原
