Abstract：A method of determining the contents of K，Na，Ca，Mg，P，Zn，Al，Ba，Co，Cu，Ni，Sr，Cr and Ti, fourteen elements, in urine of Xinjiang Kuitun fluorine poisoning and arsenic-fluoride poisoning patients was developed.The operation conditions of ICP-AES, and the lowest test concentration，precision and linear ranges were studied.The relative standard deviation of the method was 0.24%-2.47%(n=10)，the average recoveries were 90.4%-100.5%.The contents of K and Na in urine of fluorine poisoning and arsenic-fluoride poisoning patients were higher than those of healthy contrast group.The contents of Ba，Co，Cu，Ni and Cr in the urine of arsenic-fluoride poisoning patients were higher than those of fluorine poisoning patients and healthy contrast group(P＜0.05).The contents of P，Ca，Mg，Zn，Al，Sr and Ti do not have statistic significance(P＞0.05).The method was sensitive，simple and accurate.The experiment data was reliable.
