Jan 30, 2016 The aim of this research work is to develop a novel cost effective strategy for fluoride removal, applicable to rural areas of developing countries. Most of the adsorbent based technologies for fluoride removal work at acidic pH which is not a feasible condition for application in rural areas. This study investigates the feasibility of three low-cost adsorbents (calcium carbonate, activated ...

Calcium looping (CaL), or the regenerative calcium cycle (RCC), is a second-generation carbon capture technology. It is the most developed form of carbonate looping, where a metal (M) is reversibly reacted between its carbonate form (MCO 3) and its oxide form (MO) to separate carbon dioxide from other gases coming from either power generation or an industrial plant.
