“…One of the other surface active simple polymers is poly[N,N -bis(3-silsesquioxanilpropyl)-thiocarbamide] (PSTM-3T) which was synthesized [8] and investigated for determination of noble metals of gold, platinum, and palladium [9]. Previously, we revealed the adsorption kinetics for removal of Cu(II) and Cr(VI) ions from the wastewater using PSTM-3T polymer [10,11].…”

The synthesized poly[N,N′-bis(3-silsesquioxanilpropyl)-thiocarbamide] (PSTM-3T) was used and the surface morphology and microstructure of it were analyzed by scanning electron microscopy with energy dispersive spectrometer (SEM/EDS). The molecular structure change of the PSTM-3T polymer of the PSTM-3T after treatment by acidic solution with different pHs was revealed using FT-IR experiments andab initiocalculations with density functional theory method. The sorption efficiency of the heavy metal ions depends on the molecular structure change of PSTM-3T after treatment of different pH aqueous solutions. After the treatment of acidic solution (pH = 2) of PSTM-3T, the polymer formed the tautomer state to increase the sorption efficiency for chromate ion. For the increment of pH value for acidic solution, the PSTM-3T polymer was dissociated to increase the sorption efficiency for copper ion.

In present work, low content gold in copper ores was determined by using enrichment method. Complexing polymer sorbent (polystyrene-azo-thiazandithion-2,4) was used to increase the gold content for analysis of waste copper, copper ore and copper concentrate to upgrade the methodology. The optimum conditions of the volume capacity, pH, temperature, and time dependence enrichment of gold content were examined to increase analysis efficiency by using treatment of complexing polymer sorbent. The chemical interactions and molecular structure of PSTDT with gold were successfully determined using by FT-IR and theoretical calculations.
