Characterization of natural organic matter from Mediterranean coastal seawater

Characterization of natural organic matter from Mediterranean coastal seawater

Natural organic matter (NOM) is a complex mixture of organic compounds present in all fresh water. NOM is usually only roughly characterised through conventional analytical techniques. In this study, advanced analytical techniques such as XAD fractionation, LCOCD, EEM fluorescence and membrane separation have been applied for NOM seawater characterization. Conventional analyses have shown that ...

Removal of natural organic matter from aqueous solutions by electrocoagulation

Natural organic matter (NOM) affects some qualitative parameters of water such as color. In addition, it can deteriorate the performance of water treatment process including coagulation, adsorption, and membranes. NOM also reacts with chlorine in the chlorination process and may form disinfection by-products. The present study was carried out in laboratory-scale in a batch system using a cylind...

Determination of trace metal complexes by natural organic and inorganic ligands in coastal seawater.

It is well-documented that organic compounds form strong complexes with most metals in aquatic systems, and that seawater is a complex medium which contains a large variety of organic and inorganic ligands, including colloidal matter. We suggest that most trace metals are complexed in seawater and that some inorganic metals complexes are either labile or not stable. In contrast, metal-organic c...

Natural organic matter adsorption from aqueous solutions using powdered activated carbon

ABSTRACT Introduction: Due to environmental and human health concerns related to humic acid (HA), mainly leading to disinfection by-products creation, removal or reduction of this matters is a necessary for drinking water suppliers. Based on resistive economy map road and move to self-sufficiency, it is necessary to produce our need in water treatment industry. One of the main co...
