Arsenic is a highly toxic metalloid that forms different chemical states in nature, including arsenate and arsenite, as common inorganic forms. Exposure to arsenic may cause adverse effects on human health and the environment. Therefore, the detection of arsenic is critical. Exploring new

The present study aimed to extract pesticide residues in the field and greenhouse-grown tomatoes and homemade paste based on the  (QuEChERS) method before being determined by liquid chromatography-mass spectrometry (LC-MS). The mean difference in percentage reduction of

The continuous exposure of the environment to carcinogenic wastes and toxic chlorophenols such as pentachlorophenol (PCP) and 2,4,6-trichlorophenol (TCP) resulting from industrial production activities is become a great concern. The search for cost efficient and ecofriendly approach to

In the last few years, using chemical insecticides to control the malaria vector has caused environmental pollution and resistance to chemical insecticides. This study aimed to investigate the chemical analysis of essential oils of

The behavior of phenol was studied and determined using the modified carbon paste electrode (MCPE) with nickel oxide nanoparticles doped by nitrogen carbon quantum dots as nanoadsorbent (NiO - NCQD) and cyclic voltammetry (CV). The MCP electrode was manufactured in a laboratory. The

In recent years, numerous researchers have concentrated on the process of turning waste into usable materials. Polystyrene and its modifications have received great attention over the past few decades due to their outstanding ion exchange behavior toward various toxic heavy metals in aqueous

This study focused on the adsorption behavior of the cationic Crystal
Violet (CV) dye from aqueous solutions using a Co⁺²‒hectorite
composite as an adsorbent surface. The initial and equilibrium CV dye
concentrations were determined using a UV-Vis spectrophotometer.
