The results showed that the different mass concentration of HPAM's absorbance decreases slightly when the PH value of the buffer solution is 5.0, but its reproducibility is better;In order to make the absorbance become more stable, the reaction time was identified adding proper quantities of bromine water, sodium formate and starch-cadmium iodide reagent to the solution separately; the mass concentration curve of the HPAM was draw, by means of the straight degree of the curves, the coincidence degree of the straight line about the concentration of every sampling point and so on , it shows that the mixer has good mixed effect compared with the standard curve.
如下是一些主要问题:1)文章的行文格式。文章没有按照一般科技论文的表述方式,如1是引言,2是常用方法,其实这都应该是第一部分引言里应该介绍的,引言中应扼要介绍文章的研究背景、目的,意义,采用的主要方法等。还有3是实验装置,4是实验步骤,应该这些都是第二部分,试验材料与方法。2)文章的内容。文章应主要介绍本研究的具体内容,但是本文没有,如3 实验装置部分,这个721分光光度计的原理与论文内容联系不大,根本没必要介绍,标准曲线的研究应该放在最前面等。3)文章的表述不清。如HPAM是何物,文章一直没有介绍,什么曲线的直线度、浓度与直线的重合度、什么加入溴水后的时间,应该是反应时间,总之表述不清! 4)文章的图表。图标绘制的很难看。如图2,应该纵坐标起始点从0.25开始,这样图形就会美观很多,图3又没有纵坐标标注,还多了一个纵坐标等。5)文章的结论。文章的结论中有些严格来说不是结论,而是实验中的现象与操作注意事项。
