Surface-Complexation modelling for describing adsorption of phosphate on hydrous ferric oxide surface
Mengistu, Haile A.; Tessema, Abera; Demlie, Molla B.; Abiye, Tamiru A.; Røyset, Oddvar (Journal article; Peer reviewed, 2015)Adsorption of dissolved phosphate onto synthetic hydrous ferric oxide (HFO) was measured in the laboratory as a function of pH, ionic strength, and phosphate relative concentration. Experimental data were used to constrain ... -
Vurdering av utlekking av PAH og tungmetaller fra sjøbunnen utenfor kaiområder i Indre Ranfjorden
Øxnevad, Sigurd; Røyset, Oddvar; Schaanning, Morten (NIVA-rapport;6672, Research report, 2014)NIVA har undersøkt utlekking av PAH og tungmetaller fra sjøbunnen utenfor fire kaiområder i Indre Ranfjorden i Mo i Rana. Det ble også gjort en undersøkelse for å kvantifisere hvor mye tungmetaller og PAH som tas opp av ...
