摘要：
利用比表面积分析仪（ BET ）、 X 射线光电子能谱仪（ X P S ）研究了水稻秸秆生物炭的结构 与性质,考察了吸附时间、固液比、 pH 等因素对生物炭吸附性能的影响,并探讨了生物炭材料对 Pb2＋的吸附机理.结果表明：水溶液的pH 值是影响生物炭吸附能力的关键因素;吸附过程符合准 二次动力学方程,等温吸附过程符合Langmuii？方程式,并且通过Langmuii？方程式求出其最大吸附 量高达60. 57 mg/g ;水稻秸秆生物炭对P b2 ＋吸附是以化学吸附为主.

摘要：
The farmland soil and creek sediments in different depth in the mining area were sampled, and their content of 238U,226Ra and 232Th were determined by gamma spectrometric method to assess the impact of the soil environment by single index method. The result shows 232Th was not influenced on soil in survey area. 226Ra influenced more seriously than 238U on farmland soil, meanwhile, the farmland soil at downstream of tailings dam was contaminated seriously by radionuclides than at other places. For creak sediments ,adit water resulted in more serious pollution by 238U than 226Ra, however, tailings erosion resulted in more serious pollution by 226Ra than 238U.
