Boron separation from Si–Sn alloy by slag treatmentRowaid Al-khazraji1,2,Ya-qiong Li1,2,Li-feng Zhang1,21. School of Metallurgical and Ecological Engineering, University of Science and Technology... a purification process for metallurgical-grade silicon(MG-Si) in which Si is alloyed with tin(Sn) and Ca O–Si O2–Ca Cl2 slag is used to remove boron(B) impurity. Acid leaching was performed to remove the Sn phase......
was developed.This combination links the high separation power of HPLC and high sensitivity of ETV-ICP-AES.The 2-ethylhexyl hydrogen 2-ethylhexylphosphate(P507)resin was used as stationary phase for the separation of metallic impurities in order to eliminate severe spectral interferences of the matrix.The dilute nitric acid was adopted as mobile phase for eluting Cu,Mn,Ni and La.The separation process can......
