我国部分地区饮用水中钙含量的调查分析

【摘要】 目的:检测我国部分地区居民饮用水中钙离子含量,测定水作为钙源可为我国居民提供的钙含量。方法:采用随机抽样方法分别对五个地区、每个地区的五个采样点进行水样采集,采用原子吸收分光光度法测定水中钙离子浓度。结果:检测出采样地区居民饮用水中钙离子浓度范围在13.5—96.5mg之间。结论:采样地区的居民饮用水作为钙源每天可以给居民提供的钙含量在27—193mg之间。更多还原

【Abstract】 Objective:To determine calcium content in drinking water in some regions of China by measuring calcium ion content.Methods:There were five sampling points in each one of the five regions.We sampled the water sampling in these points randomly,and detected the concentration of calcium ion by atomic absorptionspectrophotometry.Results:The concentration of calcium ion was range from 13.5 milligram to 96.5 milligram.Conclusion:Drinking water in these sampling areas could offer calcium as a source of calcium,and the daily calcium content was range from 27 milligram to 193 milligram.更多还原
