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...
Background and purpose: Access to safe drinking water is of the utmost importance in public health around the world. Presence of contaminants, such as secondary bacterial growth and endotoxins could reduce the quality of water resources. This study aimed at investigating the occurrence, seasonal variation, and removal of endotoxins in a conventional water treatment plant (WTP) in Tehran, Iran. ...
In natural photosynthesis, the oxygen evolving center is a tetranuclear manganese cluster stabilized by amino acids, water molecules and counter ions. However, manganese complexes are rarely exhibiting catalytic activity in water oxidation conditions. This is also true for the family of water oxidation catalysts (WOCs) obtained from POM chemistry. We have studied the activity of the tetranuclea...
Up to now, lots of materials such as active carbon, iron, manganese, zirconium, and metal oxides have been widely used for removal of dyes from contaminated water. Among these, ferrite nanoparticle is an interesting magnetic material due to its moderate saturation magnetization, excellent chemical stability and mechanical hardness. Graphene, a new class of 2D carbonaceous material with atom thi...
