Biochars are obtained by biomass pyrolysis, whereas activated carbon is a biochar that has undergone chemical or physical activation. Owing to the large surface area and easy surface modification both solids are widely applied as adsorbents. They are low-costs materials, they could be regenerated and their disposal is not troublesome. Adsorption of heavy metals, dyes, pharmaceuticals on the surface of biochars and activated carbons, from simple systems of adsorbate containing only one compound, are described extensively in the literature. The present paper provides an overview of reports on adsorption of inorganic and organic compounds onto these two types of adsorbents from the mixed adsorbate systems. The described adsorbate systems have been divided into those consisting of: two or more inorganic ions, two or more organic compounds and both of them (inorganic and organic ones). The research of this type is carried out much less frequently due to the more complicated description of interactions in the mixed adsorbate systems.
生物炭是通过生物质热解得到的，而活性炭是经过化学或物理活化的生物炭。由于这两种固体具有较大的表面积和易于表面修饰的特点，因此被广泛用作吸附剂。它们是低成本的材料，可以再生，处理起来也不麻烦。文献中广泛描述了生物炭和活性炭表面对重金属、染料、药物等的吸附作用，这些吸附作用来自于仅含有一种化合物的简单吸附物体系。本文综述了这两种吸附剂从混合吸附物体系中吸附无机和有机化合物的研究报告。所描述的吸附物体系分为由两种或两种以上无机离子、两种或两种以上有机化合物以及它们两者组成的体系。由于混合吸附物体系中相互作用的描述更加复杂，因此对这类吸附物体系的研究开展得较少。
