A Determination Method Of27Kinds Of Elements In Regional Water In Inner Mongolia

At present, according to relevant personage points out, has more than20only tonational targets detection of106water supply enterprises in china. The country morethan600cities only5%have the ability to detect all the indexes of water supplyenterprises, most of the lack of basic water quality testing equipment, the lack ofdetection ability. For the construction of water quality testing project requirementsimminent. Equipment plays the role of play a decisive role in the quality inspection ofthe water supply system, selecting suitable, reliable, superior testing instruments testperformance has become an important part of water quality detection.However, water quality testing unit is still concentrated in the water plant or thecorresponding inspection department, the Department has the limitation of detection.But tap water testing equipment required are equipped with the Department ofgeology, this will increase the demand for water detection testing approach. For theheavy metal pollution, the determination of fluorine content and other equipmentrequired are equipped in the Department of geology laboratory. Based on the modernsociety people of the quality of life of the increasingly high demand, the developmentof modern industrial society of pollution of drinking water more and more high, paymore attention to the safety of drinking water. But the national geological test analysisof the wide distribution, complete testing instruments, complete with some detectioncapabilities, which makes the water quality detection socialization may. Unevenmodern instrument equipment is diverse, complex types, performance, how to selectthe satisfying detection equipment safety requirements of water supply, water is noteasy to detect, because often cannot find the detection means suitable produced alaborious, time-consuming consequences.The content of this paper is to deal with the lack of water resources and InnerMongolia area detection technology and related departments on the water qualitymonitoring requirements, by the Geological Department of the existing instrumentsand testing technology resources, analyzing and detecting research on tap water of27elements. Through the detection of several instruments in the application of water Idid some experimental studies. Combined with the mineral experiments with atomicabsorption spectrometer, plasma emission spectrometry, graphite furnace atomicabsorption spectrometry, atomic fluorescence spectrometer, the extraction of a certainarea of Inner Mongolia in tap water sample: Ga, Mo, Sb, Se, W, Cu, Co, Ni, Bi, Be, Ge, In, Cr, Pb, Sc, Sn, Th, Ti, V, Zn, Zr, Mn, Cd, Ca, Mg, As, were detected in27kinds of elements such as Hg analysis. Using standard addition recoveries to monitorthe accuracy of the method. The method is accurate, reliable, stable, can be applied tothe detection of water quality demand. Sample recovery rate of Y reached100±5%;analysis and the relative standard deviation of RSD≤1%conforms to GB/T5750.2-2006Standard Test Method for water.The method is to use the organization with the equipment resources, subentrytest on metal ion in the water and harmful, and in the entire process of some nationalstandard method has made some improvements. A summary of the current waterdetection method is also made, that provide some reference to the relevantdepartments.
