Two different procedures - ligand in solution or immobilised on the solid sorbents - were evaluated as a function of pH. The selectivity order for TCPP-loaded resins was established as: Pb(II) > Ni(II) > Cd(II) > Cu(II) > Mg(II) UR - https://dergipark.org.tr/tr/pub/baunfbed/issue//261890 L1 - https://dergipark.org.tr/tr/download/article-file/228409 ER -
