We present the results of investigation of Cs(I) ion mass-transfer from outer solution into the inner part of membrane mini-reactor (MR), which is a centimeter-sized hermetically sealed pocket made of polyethylene terephthalate track membrane and filled with Prussian Blue (PB) colloidal solution. The mean size of colloidal particles was 74 $\pm$ 20 nm (98.4%) and $\xi$-potential was – (33 $\pm$ 6) mV. The pore diameter of the track membrane in the experiments varied from 50 to 50000 nm. It was found that the construction and properties of PB filled MR allow one to realize an extremely high distribution coefficient of (1.50 $\pm$ 0.05) $\cdot$10$^6$ ml/g with respect to Cs(I), which is characteristic of colloid-sized PB. Adsorption is a diffusion-controlled process localized in the pores of TM, which can be fulfilled in solution without agitation.
