Arsenic-free water still a pipedream

Bayoxide: An effective adsorbent for making arsenic free drinking water

Batch sorption experiments were carried out to remove As(III) from aqueous solution by using iron based commercial adsorbent Bayoxide. The effects of various experimental parameters, such as initial concentration, contact time and solution pH on the adsorption of As(III) on adsorbent was investigated. The adsorption density increased with increased initial arsenic concentration and contact time...

A Stochastic Still Water Response Model∗

In this study a stochastic field model for the still water loading is formulated where the statistics (mean value, standard deviation, and correlation) of the sectional forces are obtained by integration of the load field over the relevant part of the ship structure. The objective of the model is to establish the stochastic load field conditional on a given draft and trim of the vessel. Emphasi...

Arsenic - Wikipedia, the free encyclopedia

Arsenic is the chemical element that has the symbol As, atomic number 33 and atomic mass 74.92. Arsenic was first documented by Albertus Magnus in 1250.[4] Arsenic is a notoriously poisonous metalloid with many allotropic forms, including a yellow (molecular non-metallic) and several black and grey forms (metalloids). Three metalloidal forms of arsenic, each with a different crystal structure, ...

Phytofiltration of arsenic from drinking water using arsenic-hyperaccumulating ferns.

Arsenic contamination of drinking water poses serious health risks to millions of people worldwide. Current technologies used to clean arsenic-contaminated water have significant drawbacks, such as high cost and generation of large volumes of toxic waste. In this study, we investigated the potential of using recently identified arsenic-hyperaccumulating ferns to remove arsenic from drinking wat...
