Activated natural zeolites for beer filtration: A pilot scale approach

Modification of natural zeolites and their applications for heavy metal removal from polluted environments: Challenges, recent advances, and perspectives

“…Due to their structure and chemical composition, in their unmodified form, natural zeolites display an affinity mainly for cations, especially for monovalent cations, thus their applications are related to cationic pollutants [ 15 , 16 ]. However, the removal efficiency of zeolites depends both on the pollutant and zeolite characteristics [ [17] , [18] , [19] ].…”

Validation of microwave acid digestion, diffusive gradients in thin-film preconcentration and inductively coupled plasma optical emission spectrometry methodology for the determination of REEs in natural zeolites

“…Although many published papers present the chemical composition of zeolites from different deposits, the concentrations of REEs are not reported. [20][21][22][23] Inductively coupled plasma mass spectrometry (ICP-MS) and inductively coupled plasma optical emission spectrometry (ICP-OES) are two powerful spectrometric techniques for multielement analysis of trace REEs. 24,25 ICP-MS has the advantage of lower detection limits that are more appropriate for very low concentrations of naturally occurring REEs.…”
