Total vaporization solid-phase microextraction (TV-SPME) is a type of extraction technique in which a specific solvent dissolves the analyte. Then a tiny amount of solvent is taken to the vial of SPME. Then, the solvent vaporizes in the SPME vial, and sampling is carried out on the headspace of

In this study, the amino-functionalized metal-organic framework (NH₂-MOFs) was used as an adsorbent for the extraction of cadmium in rice samples based on the pipette tip solid phase extraction (PT-SPE) before determined by the flame absorption spectrometry (F-AAS). The pH of the

The negative environmental impact generated by fossil fuel has resulted in the demand to search for alternative routes of renewable sources of energy, such as biodiesel, that have unlimited duration while having little or no hazardous impact. In this study, trans-esterification of palm kernel

The present study reported the preparation of solid phases from various available and cheap natural sources represented by activated carbon to remove the polluting dye Congo Red (CR). Activated carbon derived from the leaves of the Consocarpus plant (C/AC) and Ziziphus Spina-Christi plant

The presence of pharmaceutical compounds in aqueous media, even in low concentrations, has caused adverse effects on human, animal, and environmental health. Captopril is a widely used pharmaceutical compound detected in the environment at different concentrations. Because of the concern and

As main air pollutants, volatile organic compounds (VOCs) must be paid special attention. In this study, the removal efficiency of xylene from the air was investigated by nano-activated carbons (NACs) as an efficient adsorbent and compared to commercial activated carbons (ACs). In the

Humic acid (HA) has a complex chemical composition and the ability to chelate, adsorb, and exchange ions with organic and inorganic contaminants in bodies of water, which worsens water quality and poses a threat to human health and the environment. In this research, an Ultraviolet-activated
