Sample Preparation and Analysis of Soil Pollution

The contaminated soil sample was prepared and analyzed in order to modulate soil remediation using ozonation in laboratory. This paper presents the effect of different factors on loading efficiency with 2,4-D, MCPA and dicamba as model pollutants. As the soil samples are prepared in relatively large scale, the uniformity and storage validity have been investigated. The experimental results show that volatile temperature, dipping solvent, soil style and pollutant initial concentration have effect on the loading efficiency of soil sample. Methylene dichloride as dipping solvent is better than ethanol, but ethanol has less toxicity and more moderate. As the increasing of volatile temperature, the loading efficiency is lower. The loading efficiency increases as the increasing of mesh number of soil and the decreasing of initial organic concentration. The loading efficiency of snow-white sand is better than that of quartz sand. The uniformity of sample is good for large amount production in one batch. The loading efficiency of soil sample keeps still stable after long-term storage.
