one of the most important issues affecting environmental health and sustainable food production is application of organic fertilizers instead of chemical fertilizers. this study set out to investigate the effect of application of soil humic acid and fulvic acid on barley plant. to this end a factorial experiment was carried out on the basis of randomized complete block design with four replicat...
Introduction: Humic acids have adverse effects on the water quality, then should be removed from water resources. The aim of this study was to evaluate the effect of nitrate as a radical scavenger for removal of humic acid from aqueous solutions by electron beam irradiation. Materials and Methods: In this study, after preparation of stock humic acid solution in alkaline condition, different con...
Background : The presence of humic acid in water resources is the most health problems of many communities. In recent years, various methods have been focused on for decreasing or removing humic acid that is in water resources and is one of the Trihalomethanes (THMs) precursors. The aim of this study is investigation the use of Multi-Walled Carbon Nanotubes (MWCNTs) as adsorbent at humic acid...
Introduction: The most important affect of natural organic matters in water is their reaction with chlorine and producing of disinfection byproducts that are carcinogenic. Humic acid is most common natural organic materials of surface water. Advanced oxidation processes (AOPs) are methods for the removal of organics from aqueous solutions. Application of electron beam radiation is one of these ...
Effects of humic acid on some vegetative characteristics and mineral concentrations of Mexican lime were investigated under different salinity concentrations. Four doses of humic acid (0, 1500, 3000 and 4000 mg/kg soil) and four salinity levels (1500, 2500, 3500 and 4500 µmos) were applied on Mexican lime seedlings. Experiment was conducted as a factorial arrangement based on a completely rando...
In order to investigate the effect of vermicompost and humic acid on the quantitative and qualitative characteristics of safflower (Carthamus tinctorius L.), an experiment was conducted in a completely randomized design with seven treatments (control, 100 g vermicompost, 200 g vermicompost, 0.5 g.lit humic acid, 1 g.lit humic acid, 0.5 g.lit humic acid + 100 g vermicompost, 1 g.lit humic acid ...
In order to investigate the effects of humic acid and salicylic acid on quantitative and qualitative properties and nutrients concentrations in leaves of cotton var. Khordad, a two-year field experiment were conducted at the Tehran Agricultural and Natural Resources Research and education Center during 2018with randomized complete block design as factorial with two factors as follow: soil ap...
The effects of humic acid on poliovirus type 1 recovery from water by Zeta Plus 60S filters were investigated. The humic acid interfered by preventing virus adsorption to the filters, and the interference increased as a function of the amount of humic acid filtered. Humic acid decreased virus adsorption when filtered before the virus, but did not elute virus which had adsorbed to the filters. T...

Background: Humic acids (HAs) have adverse effects on the environment; therefore, they should be removed from the water and wastewater. The aim of this study was to evaluate the efficiency of the electron beam irradiation for removal of humic acid from aqueous solutions. Methods: Humic acid was purchased from Sigma-Aldrich Company. After preparation of stock solution in alkaline condition, d...
