Abstract

--------------------------------------------------------------------------------------------------------------------------------------------Abstract The trace elements, cobalt (Co) and manganese (Mn) were determined in the drinking water of Multan city and areas in its vicinity. For this purpose, ten water samples were collected from various points within a circle of one kilometer radius, each time around seven disposal units. Water samples were stored in sealed glass flasks at room temperature. The quality of these water samples was compared with reference samples collected from various far off places which were not affected by any disposal unit. Analysis for Co and Mn was carried out using Flame-Atomic Absorption Spectrophotometer. The highest concentration of Co (0.31 ppm) was found in New Multan disposal area, while highest concentration of Mn (0.45 ppm) was noted in Suraj Miani disposal area. The contents of Co and Mn metals in most of the points are found to be greater than permissible limits of WHO guide lines for drinking water.

巴基斯坦旁遮普邦南部木尔坦地区饮用水中钴和锰含量的水质研究

-------------------------------------------------------------------------------------------------------------------------------------------- 摘要微量元素、钴(Co)和锰(Mn)测定饮用水中城市木尔坦及其附近地区。为此目的，在半径1公里范围内的不同地点收集了10个水样，每次都在7个处理装置周围收集。水样在室温下保存在密封的玻璃烧瓶中。这些水样的水质与从遥远地方收集的参考水样进行了比较，这些参考水样没有受到任何处置装置的影响。采用火焰原子吸收分光光度计对Co和Mn进行了分析。新木尔坦的Co浓度最高(0.31 ppm)，苏拉米亚尼的Mn浓度最高(0.45 ppm)。大多数监测点的Co和Mn金属含量都超过了世卫组织饮用水指南的允许限量。
