Abstract
Through static and dynamic adsorption experiments, the Polyacrylamide (PAM) adsorption and migration behavior in two characteristics soils such as chernozem and saline soil in Daqing were studied. The migration of static adsorption of PAM in two different soils and different flow amount of PAM adsorption in the chernozem adsorption column were discussed. Experiments showed that the PAM adsorption equilibrium time in the chernozem soil was longer than in the saline soil and the adsorption amount in the chernozem soil was greater than in the saline soil. PAM was easy to reach saturation when the flow amount was large in the dynamic adsorption experiment. The introduction of inert tracer bromide ion simulated the migration of the PAM through the soil adsorption column in dynamic adsorption experiments, which provided datas for building the numerical model of PAM migration rule in soil.
Highlights
Environmental contamination by petroleum and its derivatives is a serious worldwide problem (Brahim et al, 2003)
Soil pollution will cause and promote water, air, biological pollution further, so it is the important factors that the pollutants are intaked by human body thereby affect human body health
Studying the ways that the pollutants entering into the soil, the pollutants migration characteristics and the pollution range and grasping the prevention and controlling method of soil pollution are helpful for the environmental protection and management of Daqing district
Summary
Environmental contamination by petroleum and its derivatives is a serious worldwide problem (Brahim et al, 2003). According to the above method to determine PAM in chernozem and saline soil adsorption equilibrium concentration and adsorption time.
