摘要: The study aimed at the determination of influence organic load, simulated by dissolution appropriate humic acid (HA) concentrations in water, on defluoridation efficiency nano magnesium oxide (NMgO), a nascent reactive material for groundwater (GW) defluoridation. kinetic analysis process sorption HA and fluoride (F−) NMgO showed that rate sorbate removal is function capacity sorbent not solution sorbate. Frumkin isotherm equation gave best description while Freundlich better F− sorption. interfering ions F−, from both synthetic feed water natural GW systems, was affected, when ionic specie, but negative impact presence HA, as ion, felt only initial concentration <5 mg/L. effects simultaneous quality characteristics treated significant reduction activities total inorganic carbon carbonate samples were observed.
