Abstract:

Measuring the mass concentration and distribution of copper ions in copper containing sludge is a necessary step for recovering copper ions. Therefore, it is very important to study the application of high-precision X-ray fluorescence spectroscopy in the determination of Cu ions in copper containing sludge. Due to the interference caused by the overlapping wavelength of X-rays generated by other elements and copper during the measurement process, the final Cu ion measurement results are biased. Therefore, high-precision X-ray fluorescence spectroscopy was used to study the determination of Cu ions in copper containing sludge in the Shandonggou copper mine area in Zhongtiao, Shanxi, in order to solve the problem of measurement result deviation caused by interferen PHA range of 100~300, use high-precision X-ray fluorescence spectroscopy to determine the mass concentration of Cu ions in the molten sheet and correct it. The results showed that based on X-ray fluorescence spectroscopy, the range of Cu ion mass concentration in 36 sampling point samples was measured, from the lowest 8.78 mg/kg to the highest 334.98 mg/kg. Through the drawn Cu ion mass concentration distribution characteristic map, it was found that the Cu ion mass concentration was highest in the southeast and gradually decreased towards the northwest, indicating a wide variation in Cu ion mass concentration in copper containing sludge.
