Preparation of peanut shell-like calcium carbonate from biowaste chicken eggshell and its application for aqueous Victoria Blue B removal

Chicken eggshell, a by-product of food processing, has been considered as natural waste and causes a major waste disposal problem. Recently, eggshell wastes have attracted great attention because of their rich calcium sources, and they can turn trash into treasure by rational use. In this work, peanut shell-like calcium carbonate (CaCO3) materials were synthesized with chicken eggshell biowastes as starting materials via coprecipitation method....
