We took test sample 17JCS003 and detected by ion chromatography and titration 6 times，and detection results were listed in Table 1.Through comparison experiment，cyanide in pollutionfree livestock product breeding water had lower relative standard deviation by the ion chromatography than the titration，and the recovery rate was higher and detection results had higher accuracy；the limit of detection of titration method was 0.25 mg/L（GB/T5750.5-2006），while the limit of detection of the ion chromatography was 0.001 mg/L.
