Availability of arsenic in waterbodies has posed devastating impacts to terrestrial and aquatic organisms. As such, prudent and pragmatic technologies need to be developed to troubleshoot and solve the problem of arsenic in aquatic ecosystems. This study was designed to investigate the potential use of cryptocrystalline magnesite for removal of arsenic from aqueous solution. Removal of arsenic ...

Arsenic (As) contamination in the groundwater of Bangladesh is one of the major public health concerns. It has become a challenge to remove As from groundwater and a great deal of efforts employed in this regards with limited success. Cerium oxide is one of the important medias of arsenic removal techniques. Nine units of cerium-based arsenic technology were tested with seven different well wat...

Background: Arsenic toxicity as a result of consumption of hair removal agent has been rarely seen in last few years in comparison with the past. Case Presentation: In this case report, we presented a middle age woman referred to medical toxicology department due to epigastric pain and diarrhea following ingestion of hair removal agent. Urinary test for arsenic was positive. ECG changes and ele...

A field study was conducted to determine the efficiency of Chinese brake fern (Pteris vittata L.), an arsenic hyperaccumulator, on removal of arsenic from soil at an arsenic-contaminated site. Chinese brake ferns were planted on a site previously used to treat wood with chromated copper arsenate (CCA). Arsenic concentrations in surface and profile soil samples were determined for 2000, 2001, an...

Naturally occurring arsenic in groundwater in Cambodia is a serious health concern. This study tested the efficacy of a BioSand filter amended with iron nails, Kanchan filter, as a household water treatment option with three natural arsenic-bearing groundwater sources of varying compositions and spiked with lab cultured E. coli and MS2. The effectiveness of arsenic and pathogen removal was not ...

Long time uptake arsenic will cause cancers and blackfoot disease. There are still several million people suffering from drinking arsenic ontaminated water. This work studied the performance of coupled chitosan/UF for arsenic removal and the influence of dissolved organic matter n arsenic removal with UF operation. Humic acid representing dissolved organic matter was fractionated into five grou...

In the present study electrocoagulation (EC) has been evaluated as a treatment technology for arsenite [As(III)] and arsenate [As(V)] removal from water. Laboratory scale experiments were conducted with three electrode materials namely, iron, aluminum and titanium to assess their efficiency. Arsenic removal obtained was highest with iron electrodes. EC was able to bring down aqueous phase arsen...

Ferrihydrite is effective in arsenic removal because of the considerable amount of active hydroxyl groups. Solid–liquid separation of the arsenic adsorbed ferrihydrite from aqueous solution is important for the arsenic treatment technology. Coagulation is a promising process for ferrihydrite separation. Effects of different coagulants on arsenic adsorbed ferrihydrite settlement were investigate...
