Abstract: The spectral interferences to sulphur from 16 elements(Sm, Er, Yb, La, Y, Ba, Se, Cr, Tb, Zn, Fe, Cu, Cd, K, Na and P)were studied.It was found that there were interference lines from above mentioned 16 elements at 182. 036 nm±0. 035 nm. So far the spectral interference to sulphur from matrix elements in the region of wavelength shorter than 200 nm has been seldom reported for inductively coupled plasma(ICP) source. Our results show that if the wavelength difference between interference line and analytical line is equal to or less than 0.002nm, a severe spectral overlapping interference will he seen.The results can be made use of in determining sulphur in 16 matrix elements mentioned above andavoid the spectral interference from them.
