Spectrophotometric Determination of Available Sulphate Content in Soil Samples of Jaipur District

Different soil samples were collected and determined for the concentration of sulphate content through a rapid, simple and less time-consuming spectrophotometric method. Before the estimation of the sulphate content, the sample collected was dried in air and then sieved mechanically using a 2mm mesh. The sulphate present in the different soil samples was extracted in the ratio of 1:1 using water. The sulphate anion was treated with excess barium chloride solution to produce the barium sulphate precipitate and spectrophotometric estimation of the same was carried out at 420 nm wavelength. A calibration curve was observed to be linear in the concentration range of 0.1 to 1.0 mg/l. This method is equally well utilized for determination of available sulphate in irrigation water, plant materials as well as food samples. The present paper deals with the sulphate anion present in the various soil samples collected from the Jaipur district. Citation: Rashmy Nair, Chandni Jain, Neeru Gakkhar.
