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.

Current and Funded Projects:

  • Development of compsite iron for treatment of PFAS, nitro organic compounds, chrimium, and selenium in water.
  • Development of adsorbents for filtration treatment of arsenic and lead in water.
  • Advanced oxidation treatment of nitro organic compounds.
  • Treatment of perchlorate in water using exchange resins/bio-regeneration.
  • Development of SERS sensors for arsenic analysis.
  • In-situ remediation of chromate, PFAS, and arsenic in groundwater by composite iron.
  • Stabilization/solidification of organic contaminated soil and sludge.
