摘    要:黄土中游离氧化铁是指示夏季风的替代性气候指标之一。使用经典的CBD法提取游离氧化铁实验过程烦琐,而且实验条件不同对浸提结果影响很大。本实验采用盐酸羟胺-盐酸体系在不同的温度下浸提黄土中的游离氧化铁。实验结果表明:温度对实验结果影响最大,盐酸浓度次之。与经典的CBD法进行对比,在一定的条件下可以代替CBD法,从而简化试验。

关 键 词:游离铁  盐酸羟胺  盐酸  黄土

Abstract:The free iron oxide in loess is one of important climate proxies of the summer monsoon.It is a complicated process to extract it by classical CBD method.Moreover,extraction results are very different in different experiment conditions.Experiment for extraction of free iron oxide by hydroxylamine and different concentrated hydrochloride-acids in diverse conditions has been studied.The results show that the temperature is the ultimate effect of this experiment,and the concentration of hydrochloride-acid is subordinate.Comparing it with classical CBD method,we can choose the optimal substitution of CBD and simplify the experiment process.
Keywords:free iron oxide  hydroxylamine  hydrochloride-acid  loess
