Abstract

Various materials have been used to treat wastewater recently, mostly polymeric materials. Regarding the cost of the polymer, physical conditions, and mechanical strength, it is becoming more common to use nanomaterials as filler to make it cheaper and stronger. Calcium carbonate is one of the natural materials used in various fields as a macro- to nanosized material, although its synthetic (precipitated) form is much more popular. This material is compatible with most polymers; thus, one of its most used applications is preparing the polymeric composites and nanocomposites reinforced with calcium carbonate. Non-toxicity, cost-effectiveness, biocompatibility, abundance, and other features are why researchers and industries use this compound. The literature shows that adding calcium carbonate improves adsorbents’ mechanical stability and removal efficiency (in some cases to 100%). Also, calcium carbonate size strongly affected the adsorption behavior of the adsorbents. This review covers recent research on nanosized calcium carbonate applications, whether natural or precipitated, in the forms of pure and hybrid/nanocomposites to remove water pollutants.
