DETERMINATION OF CR (III) AND CR (VI) IN WATER BY SELECTIVE SEPARATION AND PRECONCENTRATION ON HYBRID RESIN
Journal Title: Engineering and Technology Journal - Year 2022, Vol 7, Issue 4
Abstract
Simple and rapid method has been developed for separation, preconcentration and determination of Cr(III) and Cr(VI) species in water by using selective hybrid R-Cu-(OH)2 resin (HCR). The effect of pH value on the adsorbed of Cr(VI) was investigated, Cr(VI) species can be retained on the HCR and eluted by 1.0 M of NaOH solution completely while Cr(III) can not adsorbed on HCR. Chromium species before and after separation process were measured with 1-5-diphenylcarbazide by using spectrophotometer. The results showed that the capacity of HCR on adsorbed of Cr(VI) was 3.43 mg g-1. The concentration of Cr(V) determined by different between total Cr and Cr(III). The recovery of the determination of Cr(III) and Cr(VI) were ( 93.0 % to 101% ) and (93.6 % to 105 % ) respectively , while the RSD were ( 0.99% -6.18% ) and ( 1.63%-7.3% ) for Cr(III) and Cr(VI) respectively.
