【摘要】 本文采用氢氧化钛共沉淀法自高浓度食盐食品中分离出铁,再用火焰原子吸收分光光度法测定。在10%的食盐存在下,0～5μg/ml的铁,浓度与峰高成正比。本法应用于高含量氯化钠食品中铁的测定,结果满意。更多还原

【Abstract】 In this paper it was developed for the quantiative determination of iron in foods containing large amounts of sodium chloride by coprecipitation with titanium hydroxide and flame atomic absorption spectrophotometry.A linear calibration curve was obtained on the recovered amount of iron added to 10% aqueous solution of sodium chloride in the range 0 to 5 μg·g^-1This method has been applied to the determination of iron in foods high sodium chloride concentration with satisfactry results.更多还原
