AI Article Synopsis
- A new spectrophotometric method was developed for measuring trace amounts of Sn (II) ions in soil, utilizing methylene blue (MB) and activated carbon for solid phase extraction.
- The method follows Beer's law within a concentration range of 1-80 ng/mL and has a detection limit of 0.34 ng/mL.
- Key factors like type and volume of eluent, concentration of MB, pH, and amount of activated carbon were optimized to enhance the method's sensitivity, and it proved effective for soil samples.
Article Abstract
A simple and accurate spectrophotometric method for determination of trace amounts of Sn (II) ion in soil sample was developed by using the methylene blue (MB) in the presence of activated carbon (AC) as the adsorbent Solid Phase Extraction (SPE) of Sn (II) and then determined by UV-Vis. The Beer's law is obeyed over the concentration range of 1-80ngmL(-1) of Sn (II) with the detection limits of 0.34ngmL(-1). The influence of type and volume of eluent, concentration of MB, pH, and amount of AC on sensitivity of spectrophotometric method were optimized. The method has been successfully applied for Sn (II) ion determination in soil sample.
