一、腐植酸的X-射线衍射分析法 X-射线衍射分析法是研究腐植酸中二级和三级结构的极其有效的方法,借助同时测定衍射光点强度和势能的结构参数,现已可能分析一些动、植物体内类腐植酸(生物酸)结构等。 1.样品制备 X-射线衍射分析法中的制备试样迄今仍为工艺技巧,一般无常规的操作程序,很多情况需靠经验办事,样品制备是应考虑式样的量是否足够、式样的纯度,分子量温度、湿度、变形的速度、选择膨胀剂、选用摸制品或
X-Ray Diffraction Analysis of Humic Acid X-ray diffraction analysis is an extremely effective method for studying secondary and tertiary structures in humic acid. By means of simultaneous determination of the structural parameters of the intensity and potential of the diffracted light spot, it is now possible Analysis of some animals and plants in vivo humic acid (bio-acid) structure. 1. Sample preparation X-ray diffraction analysis of the preparation of the sample so far is still process skills, there is generally no routine operating procedures, many situations need to rely on experience, sample preparation should be considered whether the amount of style is enough, the purity of the style, Molecular weight temperature, humidity, the rate of deformation, select the expansion agent, the choice of touch products or
