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，硫氰酸根对溴酸茜素红褪色反应具有较强催作用，此建立了催光度法测定痕量硫氰酸根法。

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。
