1. A nuclear magnetic resonance study of dialkyldithiophosphate complexes : polycrystalline and surface adsorbed
Sammanfattning : 31P, 13C and 207Pb NMR were used to characterize different metal (Ni, Zn, Pb) dialkyldithiophosphate complexes. Eight different sodium or potassium dialkyldithiophosphate salts (alkyl groups R=ethyl-, n-propyl, iso-propyl, n- butyl, iso-butyl, sec-butyl, iso-amyl and cyclo-hexyl) were used as starting materials.

2. A nuclear magnetic resonance study of polycrystalline and surface O, O´-dialkyldithiophosphate complexes
Sammanfattning : O, O'-dialkyldithiophosphate (dtp) complexes are known to be useful collectors of e. g. ZnS, PbS and CuS minerals in froth flotation. However, the precise surface chemistry is yet not understood. LÄS MER
3. Titanium(IV) Phosphates : The Next Generation of Wastewater Sorbents
Sammanfattning : Treatment of industrial waters containing heavy metal ions is essential before being discharged into the environment. Consequently, European regulations have been established to control and limit the amount of heavy metals released. LÄS MER
