Research

Research Interest:

Physicochemical treatment and of arsenic and heavy metals in water and solids.
Interaction of heavy metals, uranium and inorganic compounds at metal hydroxide-water interface.
Fate and transport of arsenic and heavy metals in aquatic environment.

Technologies Developed:

Development of a titanium-based adsorbent for treatment of arsenic and heavy metals from drinking water (U.S. patent). The adsorbent has been used successfully for the removal of arsenic and lead in water.
Development of water purification packets consisting of ferric iron and hypochlorite and a household filtration technique for removal of arsenic in drinking water and for disinfection. The technique was successfully demonstrated and implemented in Bangladesh in the early 2000s. The water purification packets have been used in many developing countries for preparation of clean drinking water.
Development of water treatment technologies for removal of heavy metals with iron (U.S. patent). Full-scale unit was installed for treatment of contaminated groundwater.
