Inductively coupled plasma atomic emission spectrometry(ICP-AES)method is widely used in various industries because of its fast analysis speed and high detection efficiency.With the development of science and technology and the improvement of people's living demand,the domestic demand for minerals increases rapidly.Waste caused by low metal recovery in the production process also needs to be addressed.The content of gold in high Ni copper liquid samples was determined by inductively coupled plasma atomic emission spectrometry(ICP-AES).Determination of gold content in high nickel-copper liquid samples in the central control smelting system is beneficial to promote the directional enrichment and efficient extraction of gold elements in the process production.The determination range,recoveries and relative standard deviations of gold in high nickel-copper liquid samples by inductively coupled plasma atomic emission spectrometry(ICP-AES)were 0.021~4mg/L,94%~98.6%and 3.7%~10.6%,respectively.The determination of gold element in high nickel-copper liquid samples by inductively coupled plasma atomic emission spectrometry(ICP-AES)is helpful to improve the determination method of gold element in high nickel-copper liquid samples,improve the measurement accuracy,and promote the process improvement.
