Conventional treatment methods are used in the of drinking water to protect human and environmental health. These can be named aeration increase amount oxygen, precipitation, chemical treatment, filtration, chlorination for disinfection. Besides, iron manganese removal operations performed places where hardness is very high depending on geographical location, cases content high. Drinking, techn...

These days, environmental pollution, notably water has increasingly caused severe human health problems. The major pollutants are heavy metals. MnFe2O4/GO nanocomposite was prepared in the current work via situ method and tested to remove lead ion Pb2+ neutral red (NR) dye from water. characterized using different techniques, including X-ray diffraction, transmission electron microscopy, Fourie...

this study aimed to develop techniques for purification of cyanotoxins dissolved in water -particularly those produced by microcystis aeruginosa species - using natural clay, chemically modifiednatural clay, commercial clay and ion exchange and adsorbent resins. except for natural clay, chemical pretreatment was required to increase the adsorption capacity of the treatment materials. all the cl...

Introduction: Natural organic matters (NOMs) existing in water resources led to various problems such as formation of disinfectant by-products (DBPs). Humic matters like humic acid (HA) are component of NOMs that should be removed from water. Advanced oxidation process (AOPs) is one of the NOMs removal methods. The aim of this study was to survey the degradation of humic acid by electron beam i...

Objectives To determine the concentration of calcium, iron, manganese and zinc ions after the application of chelator to Enterococcus faecalis biofilms. Material and Methods Fifty bovine maxillary central incisors were prepared and inoculated with E. faecalis for 60 days. The following were used as irrigation solutions: 17% EDTA (pH 3, 7 and 10), 2.5% sodium hypochlorite (NaOCl) combined with 1...

Abstract The aim of the study was to select an appropriate technology for treatment groundwater with particular emphasis on effectiveness organic matter removal. technological research carried out a pilot scale 6 weeks. station supplied taken from two wells different physical and chemical composition mixtures waters. installation enabled configuration processes continuous water sampling past ea...

In Malaysia, the quality of groundwater as one main sources drinking water is deteriorated due to presence a high level manganese, which exceeds allowable values for consumption. Manganese at concentration higher than 0.1 mg/L causes staining, turbidity and bad taste problem in water, eventually can cause depletion brain dopamine syndrome motor dysfunction memory loss resembling Parkinson disea...

Manganese oxides (MnOx ) are considered to be promising catalysts for water oxidation. Building on our previous studies showing that the catalytic activity of MnOx films electrodeposited from aqueous electrolytes is improved by a simple heat treatment, we have explored the origin of the catalytic enhancement at an electronic level by X-ray absorption spectroscopy (XAS). The Mn L-edge XA spectra...
