Adsorption of roxarsone from aqueous solution by multi-walled carbon nanotubes:equilibrium and kinetics studies
1. Background Roxarsone (3-nitro-4hydroxyphenylarsonic acid) has been used widely in poultry industry for decades to control coccidial intestinal parasites and to enhance feed efficiency. Most of the added roxarsone in animal feed was excreted into the manure. Part of the excreted roxarsone entered into the soil when poultry litter was applied to farmland as fertilizer and part of the excreted roxarsone entered into animal wastewater and surface water through washing and runoff. Roxarsone can be degraded to produce more toxic inorganic forms of arsenic, such as arsenite and arsenate in the environment. It is therefore a central challenge to eliminate the Dotential risks of being exposed to roxarsone-contaminated wastewater.
