Introduction for lab report Iron in Soil and Coal Essay - 1

Introduction for lab report Iron in Soil and Coal - Essay Example Coal falls in the group of organic contaminants of soil. The iron concentration on in coal is limited compared to the iron in soil. As a result, the carbonaceous soils from coal mineral wastes provide an effective control for acidity in leachate. Iron appears in different forms in the soil. Its concentration in the soil can affect the drinking water due to the environmental concentrations in some parts of the world. This calls for the need for measuring the iron concentration in soil and coal. Various analytical methods are available for arsenic measurement in various environmental samples. Some of them include neuron activation, hydride generation atomic absorption and the inductively coupled plasma atomic emission spectrometry. Most of these approaches require expensive equipment to measure the iron concentration in soil. However, the Spectrophotometer is effective equipment in measuring the iron in coal and soil. The sample is placed in a hydrochloric acid solution followed by a measurement of Spectrophotometer using silver diethyldithiocarbamate which is the reagent that forms colour. From the colour outcome, the concentration of iron in the coal or soil is determined (Paolo Desogus
