Abstract
This paper determined calcium and magnesium in bioleaching solution of uranium ore by optimized EDTA method. This method used acid chrome blue K-naphthol green B mixed indicator after adding reducing agent hydroxylamine hydrochloride, masking agent triethanolamine and masking agent L-cysteine. This method required the concentration of calcium and magnesium more than 0.50g/L, respectively. Thus, coexisting ions did not interfere with the determination, and the titration end point was obvious. The results show that the standard addition recovery rate of calcium and magnesium is 99.15%~101.40% and 99.26%~101.18%, respectively. The relative standard deviation of calcium and magnesium is less than 3.5% with good accuracy and precision. This method is simple and fast to determine calcium and magnesium in bioleaching solution of uranium ore, and the results are accurate and reliable.
