Using acetone adds the water withdraws the atrazine in the soil, than extract with trichloromethane, after concentrated and settle to permit, use the capillary gas chromatography.
采用丙酮加水提取土壤中的阿特拉津,再用三氯甲烷萃取,经浓缩、定容后,用毛细管气相色谱法测定。
2
The capillarywater and the moisture of amended soil significantly increased.
改良后的土壤毛管持水量、含水量明显增加。
3
The soil adhesive strength is mainly composed of capillary pressure and viscous resistance of the water film, which are affected by the nature of solid surface.
