Abstract:

A simple and rapid method has been developed for solvent extraction and separation of tin (II) using O-Methylphenyl Thiourea (OMPT) as a sensitive reagent. The basis of the proposed method is tin(II)-OMPT complex formation in aqueous potassium iodate media (0.1 mol L-1) and it is extracted into chloroform. The absorbance of complex was measured at 504 nm. Beer???s law was obeyed up to 9 ?g mL-1 of tin(II). The molar absorptivity and Sandell???s sensitivity of the complex were 1.2457??104 L mol-1 cm-1 and 0.0955 ?g cm2 respectively. The stoichiometry of tin(II)-OMPT complex was 1:2 established from slope ratio method, mole ratio method and job???s continuous variation method. The stability of tin(II)-OMPT complex was >12 hours. The proposed method is free from interferences from large number of foreign ions. The proposed method was successfully applied for separation and determination of tin(II) from real samples (environmental and food), binary and ternary synthetic mixtures. Precision of method was checked by finding relative standard deviation for 10 determinations was 0.23%. Sequential separation method has been developed for separation of antimony(III), lead(II) and tin(II).
