| Abstract: | Drying process of the ultraviolet way could cause the error of analysis result.Moreover,petroleum ether will cause the pollution in the process of filtration because of its high volatility.If we put the desiccant into the volumetric apparatus directly,on one hand,it will simplify the operation and reduce the environmental pollution.On the other hand,it will not affect the accuracy of analysis result. |
