Based on the catalytic effect of thiocyanate on the oxidation of alizarine red by potassium bromate,a new catalytic spectrophotometric method for the determination of trace thiocyanate was developed.

在磷酸介质中，硫氰酸根对溴酸钾氧化茜素红的褪色反应有强的催化作用，此建立了催化法测定痕量硫氰酸根的新方法。

Alizarin complexone is obtained by the condensation of alizarin with formaldehyde solution and iminodiacetic acid in the presence of alkaline conditions.

茜素络合指示剂是在碱性条件下由茜素、甲醛和亚氨基二乙酸缩合而成。
