Humic Acid Removal in Water via UV Activated Sodium Perborate Process
نویسندگان
چکیده
Humic acid (HA) has complex molecular structure and is capable of adsorption, ion exchange, chelation with organic inorganic pollutants in water bodies, worsening quality jeopardizing human health ecological environment. How to effectively remove HA from one the research focuses this paper. In study, UV-activated sodium perborate (SPB) synergistic system (UV/SPB) was established eliminate water. The effects initial concentration, SPB dose, pH value on elimination were determined, main mechanisms synergy degradation explored. outcomes show that ratio by sole UV only 0.5% 1.5%, respectively. removal UV/SPB reached 88.8%, which can more than other systems. Free radical masking experiment proved hydroxyl produced activation active substance for removal. results UV-vis absorption spectrum, absorbance ratio, specific absorbance, excitation–emission matrix spectroscopy verified decompose mineralize HA.

Humic acid removal from aqueous solutions by peroxi-electrocoagulation process
Background: Natural organic matter is the cause of many problems associated with water treatment such as the presence of disinfection by-products (DBPs) and membrane fouling during water filtration. In this study, the performance of the peroxi-electrocoagulation process (PEP) was investigated for the removal of humic acids (HAs) from aqueous solutions. Methods: PEP was carried out for the remov...

متن کاملSodium Tripolyphosphate (TPP) Crosslinked Chitosan Membranes and Application in Humic Acid Removal
Macroor micro-porous chitosan membranes have been utilized as adsorptive membrane for the removal of metal ions, organic macromolecules or bioseparation of protein mixtures. The removal or separation mechanism is not based on physical size retention but based on the high adsorption capability of chitosan to the target solutes. For this purpose, it is important that large macro or micro pores an...
متن کاملEffect of humic acid on pyrene removal from water by polycation-clay mineral composites and activated carbon.
Pyrene removal by polycation-montmorillonite (MMT) composites and granulated activated carbon (GAC) in the presence of humic acid (HA) was examined. Pyrene, HA, and sorbent interactions were characterized by FTIR, fluorescence and zeta measurements, adsorption, and column filtration experiments. Pyrene binding coefficients to the macromolecules were in the order of PVPcoS (poly-4-vinylpiridine-...
