MER Zeolite with Remarkable Pb2+ and Cd2+ Removal Capability Cost-Effectively Synthesized from Postprocessed Natural Stellerite

This in vitro study presents a novel, cost-effective method for synthesizing MER zeolite from natural stellerite to remove toxic heavy metals like lead (Pb²⁺) and cadmium (Cd²⁺) from wastewater. The synthesized MER zeolite demonstrated outstanding removal efficiencies—99.7% for Pb²⁺ and 99.9% for Cd²⁺—across a broad pH range and in the

The role of surface functional groups of pectin and pectin-based materials on the adsorption of heavy metal ions and dyes

This systematic review examines the role of pectin and its derivatives in removing environmental contaminants, specifically focusing on how the surface functional groups (carboxyl and hydroxyl) of pectin interact with heavy metal ions and organic dyes. The review highlights that pectin-based materials can effectively adsorb pollutants through mechanisms like electrostatic
