Advanced Buffer Materials For Indoor Air Co₂ Control In Commercial Buildings, Pavithra Ethi Rajan
Masters Theses
"The following describes a novel passive approach to control the indoor CO2 levels in enclosed spaces, primarily focusing on commercial buildings. Amine impregnated silica sorbents were identified as suitable candidates and synthesized; the amine loading ratio was varied to create a range of materials. These samples along with other commercial zeolite candidates have been tested over a range of CO2 concentrations to determine the CO2 adsorption capacity in laboratory systems and under simulated room conditions. The research work also focuses on the CO2 desorption capacity of the candidate adsorbents. The desorption is allowed to occur gradually …

Removal Of Heavy Metals From Electroplating Wastewater Using Rice Husk And Coconut Coir, Frency Mathew
Masters Theses
"Heavy metal toxicity due to industrial wastewater has been a threat to the environment for the past many decades, especially in the developing countries such as India, China and Thailand where cost effectiveness of the removal process is a major factor. In this research, the effectiveness of two natural adsorbents, rice husk (RH) and coconut coir (CC), which are cheaply available in these countries for the removal of heavy metals from electroplating wastewaters were studied"--Abstract, page iii.
