The color reaction of 4-nitro-6-sulfophenolazorhodanine (NSPAR) with platinum was studied in this paper.
研究了磺硝酚偶氮若丹宁(NSPAR)与铂的显色反应,在pH为2。
5的氯乙酸NaOH缓冲介质中,吐温80存在下,磺硝酚偶氮若丹宁(NSPAR)与铂反应生成2∶1稳定络合物,该络合物可被WatersSep PakC18小柱固相萃取,用氮氮二甲基甲酰氨(DMF)洗脱后用光度法测定。
After the culture medium was steeped in 40℃ ion free water for 60?minutes ,the crude cellulase liquid was made by filtering the steeper, when the content of tannin in the enzyme liquid up to 5.
在酶活为FPase 2 2 6u/mL的稀酶液中 ,加入丹宁至 5 0g/L时 ,粗酶液中纤维素酶接近完全沉淀下来 ,将沉淀分散于 pH4 6的 0 1mol/L柠檬酸缓冲液中 ,加入分子质量为 6 0 0 0u的聚乙二醇 (PEG)至丹宁含量的 1 6～ 4 0倍 ,酶活回收率达到2 10 %～ 2 4 5 % ,可将纤维素酶浓缩 7～ 8倍。
