METHOD OF PRODUCING METAL BINDING PARTICLES BASED ON PHOSPHINE Russian patent published in 2016 - IPC C02F1/28 C07F9/50 B01J20/30 

FIELD: metallurgy.

SUBSTANCE: method of producing selectively transition metal binding particles based on phosphine includes at least a step of reacting of macroporous particles containing at least one reactive functional group "NH", interacting with at least one molar equivalent of phosphine derivative R-P(CH₂OH)₂, with a nucleophilic agent of formula NHR^aR^b. Wherein NHR^aR^b contain at least one reactive functional group "NH".

EFFECT: invention relates to a method of producing selectively transition metal binding particles based on phosphine, use of macroporous particles as reactive agent to metal binding particles on the basis of phosphine, application of metal binding particles for binding transition metal atoms and to a method of capture of transition metal atoms using particles based on phosphine.
