【摘要】 以海带干粉为吸附剂,研究了海带吸附Hg2+的性能.结果表明:海带对Hg2+有很强的吸附能力,它是不依赖温度的快速过程;吸附率与海带粉细度有关,海带粉越细吸附率越高;pH值在4~7时能保持较高的吸附率;海带投入量一定时,吸附率与起始Hg2+浓度相关,Hg2+浓度在25~250 mg/L时,吸附率随起始浓度的减小而增大.更多还原

【Abstract】 Dried biomass of laminaria japonica was used as biosorbent for Hg²⁺.The results show that（laminaria） japonica has a strong and fast absorption of Hg²⁺ without depending on temperature.The absorptivity is determined by the cubage of powder and higher at pH?4 to 7.When [Hg²⁺] is a range of 25～250?mg/L,the absorptivity mutually related with the initial concentration of Hg²⁺and increased with [Hg²⁺]（decreased.）更多还原
