Název v původním jazyce

The influence of nutrients on arsenic adsorption onto nanomaghemite

Popis výsledku v původním jazyce

The effects of the iron nano-oxide maghemite (Fe2O3) on the bioavailability of trace elements (As, Al, Cu, Fe, Mn, Mg, Zn) were tested by a set of adsorption experiments, performed with a soil solution with/without the nanomaghemite (NM) and increasing concentrations of nutrients (K, N and P). For this purpose, KNO3, NH4NO3 and KH2PO3 were added in different proportions to a soil solution obtained from an As-contaminated soil, to create a set of combination of them during NM-nutrients interaction, and study the changes in the availability of the elements with emphasis on the competition between contaminant and nutrients for the sorption sites. NM was able to decrease As concentration in a soil solution, but among the nutrients studied, the presence ofP reduced the effectiveness of the NM for As adsorption. The concentration of Ca, Mg, Mn and Na were also affected by K, N and P in the soil solution probably because of competition for the sorption sites in the NM.
