应用分光光度计测定新校区水中铁离子的含量
摘要
铁是地壳中最丰富的金属元素之一,是生活饮用水检测的感官性状指标,水中的亚铁离子在接触空气后被氧化成高铁离子,使水呈现令人厌恶的棕红色。水中铁可来自自然环境和工业废水污染,在净化处理过程中较难去除。水中含有微量铁时呈黄褐色,铁的氧化物能在水管内壁逐步沉积,在水压波动时可造成“黑水”现象。铁经常存在于天然水中,含量高时,可使衣物和固定设备染色,产生不良味道。为防止衣物、器皿被染色和形成令人反感的沉淀及异味,CB5749-2006-生活饮用水卫生标准》 mg/L。
本次课程研究用分光光度计法测水中铁的含量,以我院生活饮用水进行研究,已达到以下目的:
通过学院生活饮用水进行检测分析,深入了解和掌握该水域的环境及状况,以达到防止该水域出现重度污染。
通过对该水域周边水的水质监测,掌握该水域周边的水环境质量现状,并判断水环境质量是否符合国家有关环境标准的要求,以达到保障人们饮水健康。

Application of new campuses spectrophotometer iron content in water
Abstract:
Clip is the crust one of the most abundant metallic element,and it is detected in drinking water indicators of sensory properties, Ferrous ions in water after contact with the air oxidation of high-iron. Iron in water e from the natural environment and industrial wastewater pollution, In the purification process difficult to traces of iron in water was brown when, Iron oxide can be deposited in the water wall and gradually,Fluctuations in water pressure can cause "black water" often found in natural water content is high, can stain clothing and fixtures, resulting in bad prevent clothes, utensils to be stained and the precipitation and the formation of offensive odors, <GB5749-2006 drinking water health standards >will limit the concentration of iron in drinking water as mg / L.
The course of iron in water by method to measure the content of drinking water in our hospital to study, has the following purposes:
Institute of drinking water were detected by analysis, in-depth understanding and knowledge of the environment and the status of the waters, to prevent the heavily polluted waters.
Through the waters surrounding water quality monitoring, control of the waters surrounding th
