摘要
主要研究定量检测精矿粉中硫酸根离子的实验方法,即称取适量精矿粉,加入水后低温加热至硫酸盐溶解,过滤,定容,在滤液中加入盐酸酸化,边搅拌边缓慢加入过量BaCl2溶液,使SO42-生成BaSO4沉淀,经过滤、洗涤、干燥后,称量BaSO4的质量,计算得出硫酸根离子含量.通过实验得出,定性分析为SO42-未检出的不适用于此方法,而定性分析为SO42-检出的适用于此方法,且方法准确可靠.
Abstract
The main research focuses on the experimental method for quantitatively detecting sulfate ions in concentrate powder,which involves weighing an appropriate amount of concentrate powder,adding water and heating it at low temperature until the sulfate is dissolved,filtering,and adjusting the volume.Hydrochloric acid is added to the filtrate for acidification,while stirring and slowly adding excess BaCl2 solution to generate BaSO4 precipitate.After filtering,washing,and drying,the mass of BaSO4 is weighed,and the sulfate ion content is calculated.Through experiments,it was found that qualitative analysis indicating that SO42-undetected is not suitable for this method,while qualitative analysis indicating that SO42-detected is suitable for this method,and the method is accurate and reliable.
