Abstract:
The invention relates to a method for preparing phosphine-based selective transition metal binding particles, said method comprising at least a step of reacting macroporous particles comprising at least one “NH” reactive function reacted with at least one molar equivalent of a phosphine derivative R—P(CH2OH)2, with a nucleophile reactive agent of formula NHRaRb, wherein NHRaRb comprises at least one “NH” function.
