Implication

Experimental analysis reveals thermal treatment improves sorption of methylene blue in Kazakhstani diatomite and zeolite, indicating effective modifications.

Key Points

To experimentally assess the effects of thermal treatment on diatomite and zeolite's sorption properties and physicochemical characteristics.
Conducted comparative analysis of sorption properties of diatomite and zeolite samples.
Utilized dynamic adsorption tests for methylene blue adsorption.
Applied BET analysis, FTIR, XRD, and XRF for sample characterization.
Moderate heat treatment at 400 °C increased diatomite's surface area and sorption capacity to about 53%.
Heating to 700 °C decreased diatomite's porosity and sorption efficiency to approximately 39%.
Natural zeolite had a sorption activity of about 58%, which increased to approximately 72% after thermal activation at 500 °C.
Acid modification and calcination for zeolite raised the sorption to about 86%, surpassing literature values.
