Fluoride removal quantitatively related with surface area, porosity and density of limestone. • Fe 2 O 3 and Al 2 O 3 impurities make the pH of treated water more acceptable for drinking. • The results may help in screening limestone for use in fluoride removal by PACLT.
The current manuscript reviews show about adequacy of various materials based on calcium for removal regarding fluoride through drinking water and industrial waste water.

fluoride removal by industrial, agricultural and biomass wastes as adsorbents: review By somesh shrivastava A critical study on efficiency of different materials for fluoride removal from aqueous media
In case of LN, pH range 6–12 was more favourable for fluoride uptake from water. At a fluoride concentration of 90 mg/dm 3, the fluoride removal efficiencies of the 3 sorbents ranged between 77.0% and 85.0% .The capacities of coal based adsorbents ranged between 6.9 …
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, …
Pre-acidified fluoride water using two edible acids, viz., acetic acid (AA) and citric acid (CA) have been used for treatment by crushed limestone of diameter 3-4 mm to. precipitate fluoride as ...
Studies such as a two-column limestone reactor [13], crushed limestone [53], co-precipitation with calcium enhanced ferric hydroxides [54] and calcium phosphate hydroxyapatite [55] were reported for fluoride and arsenic removal by precipitation method. It was concluded from these

In this study, natural calcium-rich attapulgite (NCAP) was used to develop a low-cost adsorbent for removing fluoride (F−) from contaminated water. The results showed that calcination can dramatically increase the F− sorption capacity of NCAP and that the maximum F− sorption capacity occurred at 700 °C. The sorption of F− on NCAP heated at 700 °C (NCAP700) …

Calcium-based adsorbents. Calcium has a good affinity for fluoride anion and it has been used for fluoride removal [].Crushed limestone (99% pure calcite) used as an adsorbent for fluoride removal by batch studies and surface-sensitive techniques from solutions with high fluoride concentration ranging from 3 to ~2100 mg/L.
