The kinetics characteristics of mercury absorption on the Sanjiang Plain and Jilin Shuangyang peat, and the influences of temperature and pH were studied using the method of Batch. The results showed that the rate of mercury absorbed on the Sanjiang Plain peat was slower than that on Jilin Shuangyan peat. The increase of temperature could accelerate the rate of the mercury adsorbed on peat. The rate of the mercury absorption on peat was affected by pH value of the solution. The maximum absorption was got on the point of pH 6.0. High pH (pH<7) was benefit to the mercury absorption on peat Hill equitation was fit to the kinetics of mercury absorbed on peat. The absorption quantity of peat to mercury inmire wetlands was high. Low temperature and fit pH of wetland was benefit to the storage of mercury in wetland soil.
