The extraction equilibria of chromium(VI) from sulfuric acid solutions with tri-n-octylphosphine oxide (TOPO) dissolved in kerosene at 25Β‘C have been studied. The possible complexes of chromium(VI) with TOPO in organic phase and extraction constants were determined by best Γtting the distribution co

## Abstract A simple and effective method has been presented for the preconcentration of uranium by solid phase extraction. For this purpose arsenazo(III) supported on naphthaleneβmethyltrioctylammonium chloride was used as an adsorbent and uranium solution at pH 3.5 with flow rate of 1 mLΒ·min^β1^
