自然水体中生物膜吸附铅、镉的热力学特征

摘要

利用自然水体培养的生物膜进行铅、镉的吸附实验,研究铅、镉吸附的热力学特性,并比较了生物膜对铅、镉的吸附能力.%Thermodynamics properties of adsorption of Cd and Pb to surface coatings, which were developed in the surface water of Jingyuetan Lake in Changchun, China, were studied. The adsorbabilities of the surface coatings towards Cd and Pb obtained were discussed.
