Natural zeolites are abundant and low cost resources, which are crystalline hydrated
aluminosilicates with a framework structure containing pores occupied by water, alkali and …

The recovery of ammonia–nitrogen during wastewater treatment and water purification is
increasingly critical in energy and economic development. The concentration of ammonia …

This research presented six natural clay minerals (NCM) evaluated for the effectiveness of
NH 4+ adsorption from aqueous solution. For the first time, the NH 4+ adsorption capacities …

The excessive amount of ammonia presents in water streams has led to a serious potable
water scarceness worldwide. The application of conventional methods in removing …

Ammonium pollution in groundwater and surface water is of major concern in many parts of
the world due to the danger it poses to the environment and people's health. This study …

Heavy metal pollution in the environment and effects on human health is within the most
important issues. Because of continuous deterioration of water quality and persisting …

Low-cost zeolite sorbents, which have unique ion exchange and sorption properties, have
been investigated as candidates for cost-effective removal of heavy metals from waste …

Biochar is a promising immobilization tool for various contaminants in liquid wastes,
aqueous solutions and soils. To further improve the sorption characteristics, a biochar …

This paper focuses on the effectiveness of removing ammonium ion and the theoretical
aspects of adsorption including adsorption isotherm, kinetics and thermodynamics as well …

In the present study ion exchange of Pb2+, Cu2+, Fe3+, and Cr3+ on natural Greek
clinoptilolite was examined in terms of selectivity toward the above heavy metals in single …
