Background & Aims: Humic acid is a major agent in trihalomethanes (THMs) formation during chlorination process, which are known as carcinogens. The aim of this study were to investigate the removal of humic acid by three coagulants including PACl, alum and ferric chloride from water sources and their effect on zeta potencial. Materials & Methods: This study was conducted  ...
This study was carried out in order to evaluate the changes of Nitrogen, phosphor and potassium uptake by wheat and remaining of them in soil under foliar application of Leonardite and foliar application of N and K. The experiment was conducted in Gorgan University of Agricultural Sciences and Natural Resources during 2013- 2014. The experiment was laid out a using split-plot arrangement based ...
in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
H1 antihistamines constitute one of the main references for the treatment of allergic rhinitis. Classically, these drugs have been considered effective in controlling sneezing, rhinorrhea and itching, though they have not been regarded as particularly effective in application to nasal obstruction. The most recent studies, involving second-generation H1 antihistamines (desloratadine, fexofenadin...
One of the main consequences of population growth is that an equivalent food production increase is needed. To meet this basic need of society and ensure growth in food production, it is necessary the use of agrochemicals such as herbicides, preventing competition between crops and weeds for soil nutrients. This growth in use of agrochemicals has historically had undesirable consequences due to...

asymmetric membranes are widely used in many industrial membrane separation processes. the major advantage of membrane filtration over the conventional process is its ability to remove a wider spectrum of particles without using any chemicals. hollow fiber configuration offer many advantages over flat-sheet or tubular membranes. the spinning process of hollow fiber may look simple, yet it is te...
Understanding the quantity and quality of dissolved organic matter (DOM) in potential watershed sources is critical for explaining and quantifying the exports of DOM in stream runoff. Here, we examined the concentration and quality of DOM for ten watershed sources in a 12 ha forested catchment over a two-year period. DOM composition was evaluated for: throughfall, litter leachate, soil water (z...
Humic substances are defined as the result of decomposition any organic matter, and they consist mainly humin, humic, fulvic acids. Compared to humic acids acid (FA) most explored compounds. However, FAs less studied than because usually small residual quantities. Considering that its potential for bioactivity is stronger acids, current review was performed evaluate effectiveness FA application...
