Study on the extraction mechanism and thermodynamics of Pb(II) with a o-phenylendiamine tetraacetic acid Accession number: 20173704159965 Authors: Wang, Junwei 1 ; Zhang, Dan 1 ; Dong, Yanjie 1 ; Lu, Lu 1 ; Wang, Wei 1 ; Zhang, Yuanguang 1 Author affiliation : 1 College of Chemistry and Chemical Engineering, Anhui Key Laboratory of Functional Coordination Compounds, Anqing Normal University, Anqing; 246011, China Corresponding author: Dong, Yanjie (dongyjaqtc@163.com) Source title: Russian Journal of Non-Ferrous Metals Abbreviated source title: Russ. J. Non-ferrous Met. Volume: 58 Issue: 4 Issue date: July 1, 2017 Publication Year: 2017 Pages: 351-356 Language: English ISSN: 10678212 E-ISSN: 1934970X Document type: Journal article (JA) Publisher: Allerton Press Incorporation Abstract: The extraction mechanism and thermodynamics of Pb(II) with a novel o-phenylendiamine tetraacetic acid (H4PDTA) were studied by high performance liquid chromatography with UV detector. The effects of extraction time, reciprocating oscillation frequency, Pb(II) concentration, H4PDTA concentration and Pb(II) solution acidity on Pb(II) extraction were investigated. The results showed that the extraction ratio of Pb(II) increased with an increase of pH and H4PEDTA concentration with a reciprocating oscillation frequency of 120 CPM (cycles per minute). The composition of the extraction complex was determined by slope methods and UV spectral analysis. The extraction mechanism of Pb(II) was proved to be a chelate extraction reaction and the values of thermodynamic function at 25°C were determined: Kexˉ = 2.18 × 103, ΔGr= –19.05 kJ mol–1, ΔHr= –9.965 kJ mol–1and ΔSr= 30.47 J mol–1K–1. © 2017, Allerton Press, Inc.
