Outline
An on-line analyzer was developed for the determination of carbonate and hydrogencarbonate concentrations in the tail liquid of a fluorine-leaching agent by titrimetry with the electrode measuring pH as the end point, the chemical principle, hardware composition, determination program and other functions of the instrument were introduced. The alkalinity of 0.01~1.00 mol/L was determined by the instrument. The repeatability error is 1.5%, the accuracy error is 4.8% and the lower detection limit is 0.04 mol/L. The results of field test show that the instrument has good stability and high precision, and the measured data are basically consistent with the on-site titration analysis data, which meets the requirements of on-site analysis. The recovery rate of spiking is between 96.0% and 104.0%.
