Abstract

This is a green method for determination of mercury ion (Hg²⁺) in environmental samples. The method of exchangeable water based on liquid-liquid microextraction (EW-LLME) was first time introduced as a green analytical separation technique. Exchangeable water was made by the reaction of carbon dioxide with diethylenetriamine. The exchanging phenomena from low polarity to high polarity were confirmed by Fourier transforms infrared spectrometry. The complex formation between Hg²⁺ and 1, 5-diphenylcarbazone was achieved under the optimized experimental conditions. The enrichment factor and limits of detection of the present method were obtained to be 45.2 and 0.5 ng L⁻¹, respectively. The accuracy of the present method was confirmed with certified reference materials. The EW-LLME was successfully applied for determination of Hg²⁺ in solid matrices of block-III and V of Thar coalfield.
