Key words: Curcumin, boron, spectrophotometry1引言硼（B），原子序數(shù)5，自然界中硼只以其化合物形式存在，如硼酸（H3BO3）、硼砂（）等，在動物和植物中存在著結合態(tài)的痕量硼。關鍵詞：姜黃素，硼, 分光光度法The study of analysis method for determination of boron with curcumin spectrophotometry (one)Sun GuotaoDepartment of chemistry, College of Science,Hebei North University, Zhangjiakou Hebei 075000Abstract: This paper established the optimum conditions of determinating boron with curcumin spectrophotometry, discussed the effect of different factors on the results, and provided a reference for the curcumin spectrophotometric determination of boron content. For experiments, the curcumin was as chromogenic reagent, the alcohol was as the medium, the absorbance was determated in the water bath evaporated experiments optimized the chromogenic conditions and studied the influence of different factors such as acide, salt and solvent on the method. The optimun experimental conditions are: the curcumin dosages of 4mL, the chromogenic time of 15min, the water bath temperature of 55 177。C，顯色測定時間在4天以內(nèi)。實驗得出的優(yōu)化條件為：顯色劑用量4mL，最佳顯色時間為15min，最佳水浴溫度55 177。姜黃素分光光度法測定硼的分析方法研究畢業(yè)論文目錄1引言 22原理 33儀器及試劑 3 3 3 34分光光度法測定 4 4 45結果與討論 4 4 4
