| 摘 要： | 在腐植酸钾分子上引入了其他基团,可使改性腐植酸钾的结构发生变化.用72-1分光光度仪可以定量测出:在一定时间内,随着生成改性腐植酸钾质量分数的增加,溶液的光密度减小;在制备过程中,改性腐植酸钾溶液的光密度随时间的变化规律呈线性负相关。 |
| 关 键 词： | 改性腐植酸钾 光密度 线性相关 |

| Abstract: | Because some other groups are introduced into the molecule of KHm, KHm's structure is changed. Using the 72-1 spectrophotometer, it can be measured quantificationally that the optical density of the solution decreases while the mass fraction of the modified KHm increases. During the course of preparation, the mass fraction of modified KHm solution changes as the reaction time changes, and the varying relationship between the optical density of modified KHm solution and the mass fraction of modified KHm solution is negative linear correlation. |
| Keywords: | modified KHm optical density linear correlation |
