Combustion by-products of coal from thermal power plants cause environmental pollution;
efforts are made to develop techniques and green processes that could reduce the waste …

Attapulgite (ATP) is a type of natural magnesium aluminum silicate mineral and has been
applied as an adsorbent to remove organic pollutants and heavy metals in aqueous …

A cancrinite-type zeolite was synthesized from Class C fly ash by molten-salt method. The
product (ZFA) was used as the adsorbent for the arsenate removal from water. The …

The modified zeolite A was prepared by a two‐step crystallization method to remove scale‐
forming cations from water and geothermal water. The adsorption kinetics, mechanism and …

Diatomite-based X zeolite was obtained and its crystallinity, morphology, and interface
properties were investigated by XRD, BET, SEM, EDS, and XRF. The obtained X zeolite …

Abstract 5A zeolites were facilely synthesized from attapulgite clay and sodium aluminate
precursors. The optimum synthesis condition for 4A zeolite (Na-form) were H 2 O/attapulgite …

To develop an effective technique for enhancing the removal efficiency of ammonium and
phosphate at low concentrations without losing potential removal capacity, Na-ZFA (zeolite …

Coal fly ash is a typical secondary aluminum/silicon resource. The preparation of zeolite-
type absorbent is a potential way for its value-added utilization, while the purity and …

Na-A zeolite was synthesized using oil shale ash (OSA), which is a solid by-product of oil
shale processing. The samples were characterized by various techniques, such as scanning …

The incorporation of steric effects into the hydrothermal synthesis system of NaA zeolite
proves to be an effective method for modifying grain size, enhancing grain dispersion and …
