| 1 | Development of Chromium(Ⅲ)-selective Potentiometric Sensor by Using Synthesized Pyrazole Derivative as an lonophore in PVC Matrix and its Applications显示文摘A novel poly(vinyl chloride)membrane potentiometric sensor for chromium(Ⅲ)ions based on the use of 5,5′-(1,4-phenylene)bis(3-(naphthalen-1-yl)-4,5-dihydro-1H-pyrazole-1-carbothioamide)as a neutral ionophore was developed.The optimum composition of the best performing membrane contained ionophore,potassium tetrakis(p-chlorophenyl)borate(KTpClPB),dibutyl phthalate(DBP),and poly(vinyl chloride)(PVC)in the ratio of 5.5:1.5:55:38(mg).The sensor exhibits a working concentration range of 1.0×10^(-5)-1.0×10^(-1 )mol L^(−1) and a detection limit of 1.7×10^(-6) mol L^(−1).The sensor shows good selectivity for chromium(III)ions over a number of cations including alkali,alkaline earth,heavy and transition metals.The response time of the sensor is 8 s.In addition,the developed sensor shows good reusability and stability.The sensor operates in the wide pH range of 5.0-11.0.The sensor could be used as an indicator electrode in the quantification of Cr^(3+)ions by potentiometric titration against ethylenediaminetetraacetic acid(EDTA).Finally,this sensor was successfully used for the determination of chromium(III)in commercial water,purification water and wastewater. | Ömer Isildak OguzÖzbek Meliha Burcu Gürdere | 2020 | Journal of Analysis and Testing2020，4，4： | 2 |
