It is proposed and confirmed in industrial test that the concentration of Al in the liquid phase can be minimized via adjusting the conversion rate of the carbonization of potassium chromate.

提出了通过调整K2 CrO4 碳酸化反应转化率来降低体系中Al杂质含量的新方法，工业试验已证明了其可行

Methods: The protein and other impurity in the sample were precipitated by zinc acetate and potassium ferrocyanide after dipping of the sample. N,N-dichlorocyclohexylamine derived from sodium cyclamate by sodium hypochlorite in the filtrate was extracted by hexane. The HPLC separation was carried out with a phenomenex Gemini-C18 column using acetonitrile-water(7+3) or methanol-water (8+2) as mobile phase and detected by UV monitor at 314 nm. External standard method was used for quantification.

样品中甜蜜素浸提后，用乙酸锌和亚铁氰化钾试剂沉淀蛋白质等干扰杂质，过滤，用次氯酸钠将样品溶液中的甜蜜素转化为N，N-二氯环己胺经正己烷萃取后，在phenomenex Gemini-C18柱上，以乙腈－水(7+3)或甲醇－水(8+2)为流动相进行分离，HPLC-UV检测器在314 nm测定，外标法定量。
