Effects of quenching methods on HAA determination in chloraminated waters

This study investigated how determination of haloacetic acid (HAA) in chloraminated samples was affected by use of ammonium chloride (NH4Cl), the chlorine quenching agent recommended in US Environmental Protection Agency method 552.3. Alternative quenching agents and methods were also examined

Regeneration strategies for spent solid matrices used in adsorption of organic pollutants from surface water: a critical review

Adsorption is a very important physicochemical process used for several purposes including separation and purification of proteins and in water treatment. This article reviews the various strategies that have been employed in the regeneration of spent adsorbents used in the adsorption of organic pollutants from aqueous solutions. The principles, advantages, disadvantages, and factors influencing each of these techniques are discussed. Future perspectives on the use of these techniques in regeneration process are provided for further studies with the view to make the regeneration process of spent solids more efficient and sustainable
