An investigation of the some lanthanoides and actinoides adsorption/desorption onto surface of typical mineral soil components-laminated and laminated-ribbon silicates in the presence of the humic matter. Investigation methods: spectrophotometry, roentgenographic analysis, ultrafiltration, radiometru. Techware: some physic-chemical aspects of surface complexes formation in the aqueous media between the some of lanthanoides or actinoides and most widely spreaded natural organic species-fulvic acids, involves natural and modified minerals were studied. An acid properties of functional groups of the fulvic acids was indicated as afecting, the nature of the surface active centers was estimated on account of their role as radical to migrate the radionuclides and heavy metals in the environment. Complex surfac e compounds in a system of Ln(Ac)-clay mineral-humic substances envolves the organic ligands(Fulvic acids) is shown to form. The character of the metal sorption in the presence of the FA, however, controls preferentially by the chemical nature of an element, its concentration and Me:FA molar ratio as well. An ultrafiltration technique was examined to uranium - containing sewage decontamination, a number of the parameters were studied for their effect on this process. Polyethylenimine was shown as high effective to uranium decontamination (the degree of purification reach up to 99,8%). Protection of an environment atomic engineering.
