Hi, everyone.

I have to design column adsorption to investigate removal arsenic from drinking water, but now I haven't known how to design yet. If you know or have literature about it, show me please.

Thanks a lot.

Hi dailan,

There are many ways to adsorb arsenic from drinking water.  Unfortunately, all of the adsorption media have different rates of adsorption.  You may want to try 'active carbon', it is also called activated charcoal.  When designing the column, you will want to determine efficiencies by monitoring retention time, particle surface area, pH, and other trace elements which have been removed.

I hope this helps,

Eugene
