Abstact
	The basic experiments were realised for possibility of copper removal from wastewater using non-traditional adsorbents, which are less costly. A large number of low-cost adsorbents for heavy metal ions removal is available. Kinetics of adsorption onto small particles of about 1 mm is relatively slow. Kinetics may be increased by using smaller particles that leads to greater pressure loss in the adsorption bed. 
	Adsorption is autonomic increase of the concentration of some matter on the interface of phases. Adsorption is realised on fluctuant (liquid) or solid interface of phases. Fluctuant interface of phases is created with contact of two non-mixing liquid phases. Solid interface of phases is created with contact of solid phase and liquid phase that can be gas, steam or fluid. Adsorption onto fluctuant interface of phases is used less in practise than adsorption onto solid interface of phases.
	On the heterogeneous interface of phases the surface of solid interface (adsorbent) energetically actively influences the entities (molecules, atoms, ions) of the surrounding liquid phase (adsorptive). According to the nature of forces impacting between the entities of the adsorbent and the adsorptive there are two utmost adsorption types: physical adsorption and chemisorption, whilst the intermediate type is ion adsorption (electroadsorption).
	The following adsorbents of heavy metals were tested:
* Chitosan, deacetylated form of chitin, which can be found in crustacean shells, made by Apollo, Quindao, China, with degree of swelling 194,6 weight % in water at pH = 6,0. 
* Lewatit S100, a synthetic ionexchanger made by Bayer AG, Germany, with degree of swelling 133,3 hm. % in water at pH = 6,0.
* Synthetic zeolite, prepared by zeolitisation of fly ash.
