Abstract

Removal of Fluoride Using Brick Chip by Adsorption Prepared from Laterite Soil Area of Bihar and Jharkhand

Highlights

  • Fluoride ion exists in natural waters and it is an essential micronutrient in humans in preventing dental caries and in facilitating the mineralization of hard tissues, if taken at a recommended range of concentration

  • The term late rite is used as a common name for iron oxide rich tropical soils, which have been formed under weathering of rocks under strongly oxidizing and leaching conditions that leads to the removal of silica, alkalis and alkaline earths

  • Marginal variation in Fluoride removal by brick powder over pH range of 2 to 10 indicates its usefulness for removal of Fluoride in the pH range normally encountered in ground waters laden with Fluoride

Summary

Introduction

Fluoride ion exists in natural waters and it is an essential micronutrient in humans in preventing dental caries and in facilitating the mineralization of hard tissues, if taken at a recommended range of concentration. Excess fluoride in drinking water is prevalent in all of the Jharkhand regions of our country. The term late rite is used as a common name for iron oxide rich tropical soils, which have been formed under weathering of rocks under strongly oxidizing and leaching conditions that leads to the removal of silica, alkalis and alkaline earths. This process, referred to as Late risation, leads to an accumulation of sparingly soluble compounds as the more soluble constituents of the parent rocks are leached out.
