PROBLEM TO BE SOLVED: To reduce arsenic ions and/or arsenous ions contained in water to arsenic to remove the same without using a large amt. of chemicals, generating a large amt. of sludge and performing troublesome operation such as periodic regeneration treatment by a chemical agent.TSUNODA ...
Arsenic pollution of drinking water is a concern, particularly in the developing countries. Removal of arsenic from drinking water is strongly recommended. Despite the availability of efficient technologies for arsenic removal, the small and rural communities in the developing countries are not capable o...
Contamination of natural waters with arsenic, which is both toxic and carcinogenic, is widespread. Among various technologies that have been employed for arsenic removal from water, such as coagulation, filtration, membrane separation, ion exchange, etc., adsorption offers many advantages including simpl...
The removal of arsenic in micro-polluted water by enhanced coagulation was studied with poly ferric sulfate(PFS) and poly aluminum chloride(PAC).The effects of pH, dosage of coagulant and oxidant, initial concentration of arsenic and initial turbidity on the removal efficiency of arsenic were discu...
Portland cement has been used as a new lowcost adsorbent for the removal of arsenic from the water environment. In the batch experiments conducted at an initial concentration of 0.2 mg 11 of arsenate, it was found that up to 95% of arsenate could be removed. Kinetic profiles were developed...
These studies indicate that laterite promises to be a suitable adsorbent for use in POU devices in evolving a cost effective solution for the removal of arsenic from drinking water to the rural community. 展开 会议名称: Indian Chemical Engineering Congress, CHEMCON 2008, Punjab University, December...
The presence of silicate significantly reduced the arsenic removal efficiency of HIOPs, AA, and GFH, presumably due to the decrease in chemical binding affinity of arsenic in the presence of silicate. Additional experiments with natural types of water showed that, with the exception of IOC-M, ...
Arsenic removal from drinking water by reverse osmosis: Minimization of costs and energy consumption 来自 掌桥科研 喜欢 0 阅读量: 22 作者: AGAIA Abejon 摘要: Arsenic is one of the most serious inorganic contaminants in drinking water on a worldwide scale. To comply with the MCL (maximum ...

The following work provides a perspective on the potential application of solar heterogeneous photocatalysis, which is a nonselective advanced oxidation process considered as a sustainable technology, to assist in arsenic removal from water, which is a global threat to human health. Heterogeneous photocat...
