Introduction: Humic acid (HA) is one the original disinfection byproducts processors in water treatment. So, removing it is necessary before water chlorination. In the present study, photodegredation of humic acid in water using Ag/ZnO nano particle under UVc irradiation in batch system was investigated. Material and Methods: Photocatalytic study was carried out to evaluate the effect of UVc (...

Chitosan is prepared by the deacetylation of chitin, the second-most abundant biopolymer in nature, and has applicability in the removal of dyes, heavy metals and radioactive waste for pollution control. In weight-reduction remedies, chitosan is used to form hydrogels with lipids and to depress the intestinal absorption of lipids. In this study, an experimental method was implemented to simulat...

Contaminants in water are classified into different types based on their physical and chemical properties. Thus, more than one type of sorbents may be needed for their removal. In this article, a combination of vermiculite with palygorskite was studied for their simultaneous removal of ammonium and humic acid from simulated groundwater. Batch results showed that the Langmuir model described amm...

In recent years, in the world and in Iran as well, attention to Lisianthus flowers has been such that its production has increased significantly. With the increase in the production of Lisianthus cut flowers, attention to nutrition and application of treatments to improve the growth and storability of this flower is felt more than ever. For this purpose, the effect of karrikin, salicylic acid a...

Background and purpose: Trihalomethanes and haloacetic acids are formed through chlorination of waters containing natural organic matters and pose potential health problems. So, it is necessary to remove humic acid as the most significant natural organic matter in water. The aim of this study was to evaluate the efficiency of catalytic ozonation in removal of humic acid in presence of local...

In recent years, the development of water hyacinth (Eichhornia crassipes) has been a problem in wetlands and ponds in northern Iran. Converting water hyacinth to compost and vermicompost and its application as a growth media can be one of the effective techniques for water hyacinth control. The aim of the present study was to investigate compost of water hyacinth and application of humic acid o...

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 &nbsp...
