韩江水中铅、镉、亚硝酸根含量的测定
Determination of Lead, Cadimiun and Nitrite Content in the Water of Hanjiang River
【摘要】 利用极谱法对水中的铅、镉含量和利用分光光度对水中的亚硝酸根含量进行测定,方法简单、快速、灵敏度、精密度高、选择性好。用此方法测定的铅、镉、亚硝酸根的回收率在96-103%范围内。
【Abstract】 Lead and cadimiun content in the water is determined by polarographic Adsorptive wave and Nitrite content in the water by spectrophometry. The method is easy, rapid and economical, and its sensitivity, precision and selectivity are high. The rate of recovery of these three elements is 96-103%.
