-neutrality. The results show that the conversion rate increases in the form of "S" curve when the pH of the chromate solution decreases, and increasing the concentration of Na2CrO4 in the solution or decreasing the temperature of the solution favors the conversion rate of chromate. The experiment results indicate that the measured variation trend of the conversion rate is fairly in agreement......

to precipitate cobalt from ZnSO4 solution by ozone oxidation was proposed. The factors influencing the effect of removing cobalt, including stirring speed, temperature, gas flow rate, pH and concentrations of cobalt ion and zinc ion were investigated. The results show that the cobalt concentrations and elimination rate can reach 0.2 mg/L and 99%, respectively, under the solution conditions as initial......
