摘要

摘要: 为探索小麦麸皮吸附有害元素的能力,本实验对不同粒径范围（<0.074、0.074⁰.125、0.125⁰.425 mm）的麸皮吸附有害元素（铝、砷、铅）的能力进行研究,同时对不同粒径范围麸皮的矿物元素（钾、钙、镁、铁、锌、铜）和有害元素（铝、铅、砷、镉、铬）含量进行检测。结果表明:粒径对麸皮中的矿物元素及有害元素的含量有显著的影响（p<0.05）;在粒径小于0.074 mm的细麸皮中,被检测的矿物元素含量均为最低,宏量元素钾、钙、镁分别为7.222、0.812、2.008 g·kg^-1,微量元素铁、锌、铜分别为170、82.3、11.9 mg·kg^-1,而对于有害元素铝、铅、铬,该粒径范围的麸皮含量是最高的分别为13.7、0.1169、0.3150 mg·kg^-1,粒径为0.125⁰.425 mm的粗麸皮含有大量的宏量元素(钾、镁分别为15.867、5.984 g·kg^-1),且被检测的有害元素含量都是最低的,铅仅有0.0449 mg·kg^-1。随p H变化以及粒径的变化,麸皮吸附铝和砷的能力变化是一致的,在p H=2条件下随粒径的减小先增强后降低,而在p H=7条件下麸皮吸附能力随粒径的减小而显著增加（p<0.05）,且在p H=7条件下的吸附能力远小于p H=2;在p H=7条件下麸皮吸附铅的能力大于p H=2,且在p H=7条件下麸皮吸附铅的能力随着粒径减小而显著增加（p<0.05）,而在p H=2条件下麸皮吸附铅的能力随着粒径减小先增强后降低。综上可知,粒径对麸皮中的矿物元素含量及对有害元素的吸附能力都有显著影响。

Abstract: To study the binding ability of wheat bran to harmful elements, the ability of adsorption for wheat bran with different particle sizes ( < 0.074、0.074 ~ 0.125、0.125 ~ 0.425 mm) to harmful elements ( aluminum, arsenic, lead) was tested. In the meantime, minerals ( potassium, calcium, magnesium, iron, zinc, copper) contents and harmful elements ( aluminum, lead, arsenic, cadmium, chromium) contained by different-size brans were evaluated respectively in the study.The result showed that the particle size of wheat bran had a significant influence on the amounts of minerals and harmful elements ( p < 0.05) .All the detected contents of minerals were the lowest from 0.074 mm size bran, and the contents of macro element potassium, calcium and magnesium were 7.222, 0.812 and 2.008 g·kg^-1respectively, and the contents of trace element iron, zinc and copper were170, 82.3 and 11.9 mg·kg^-1respectively. However, the contents of harmful elements aluminum, lead, and chromium were the highest that were 13.7, 0.1169, and 0.3150 mg·kg^-1, respectively in these brans.0.125 mm to 0.425 mm size bran contained a lot of macro elements ( The contents of potassium and magnesium were 15.867 and 5.984 g·kg^-1, respectively) , and the detection contents of harmful elements were the lowest, and lead content was only 0.0449 mg·kg^-1. Under the condition of different p H and different particle sizes, the change was consistent for bran adsorption aluminum and arsenic ability. The adsorption capacity increased firstly and then decreased with the decrease of particle size at p H = 2.The adsorption capacity of bran at p H = 7 remarkable increased with the decrease of particle size ( p < 0.05) .And the adsorption capacity under p H = 7 was much smaller than that at p H = 2.The ability of bran for adsorbing lead was greater at p H = 7 than that at p H = 2. And the capacity significantly increased with the decrease of particle size at p H = 7 ( p < 0.05) . Whereas, that binding capacity to lead increased first then decreased with the decrease of particle size at p H = 2.In conclusion, particle size of wheat bran hadremarkable influences on its mineral element content and capacity of binding harmful element.
