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

Adsorption of heavy metals on natural zeolites: A review

This review examines the effectiveness of natural zeolites, particularly clinoptilolite, in removing heavy metals such as arsenic, cadmium, chromium, lead, mercury, and nickel from water. The study highlights how the mineral’s origin affects its adsorption properties and discusses methods to enhance its performance, such as acid or base treatments and
