Comparative analysis of groundnut oil quality in the north-central zone of Nigeria: Determination and evaluation of heavy metals, fatty acids, Phospho...
29/09/2023The research presents a comparative analysis of the quality of locally produced groundnut oil (Arachis hypogaea) sold in the north-central zone of Nigeria markets (Benue, Nasarawa, Kogi, Kwara, Niger, Plateau States). The aim was to assess and compare the qualities of the oils and to know the safety of human consumption. The groundnut oil produced biodiesel, shampoo lubricants, and soap-making industries. The concentrations of the heavy metals were analyzed with atomic absorption spectrometry (AAS). It showed that the lead, zinc, and copper (Pb, Zn, Cu) were within the FAO/WHO

30/09/2023Using plant essential oils (EOs) as a pesticide alternative has gained increasing interest as a promising strategy to reduce the harmful effects of chemical pesticides. This study aims to investigate the chemical composition of Eucalyptus globulus Labill and Rosmarinus officinalis L. essential oils and evaluate their impacts against Blattella germanica L. under laboratory conditions. The essential oils were prepared from dried leaves using hydro-distillation (HD) as a chemical extraction method. The gas chromatography-mass spectrometry (GC-MS) was employed to

Analytical study on lead elimination by anionic clays: Characterization, adsorption kinetics, isotherm, thermodynamic, mechanism and adsorption
30/09/2023The co-precipitation method synthesized the synthetic anionicMg–Al and Ni-Al clays with three molar ratios (Mg/Al, Ni/Al). The samples were characterized by powder XRD, Fourier transform infrared spectroscopy (FTIR), and scanning electron microscopy (SEM). No other crystalline phases were detected in the powder XRD patterns of the co-precipitated samples. The infrared spectra obtained all the functional groups that characterize these two types of anionic clays. SEM micrographs indicate the presence of particles and aggregates. The particles, or aggregates, are in the form of plates,

Starch nanocomposite containing hydroxyapatite and eggshell for absorbing methylene blue dye from aqueous solution
29/09/2023Today, polymer nanocomposites (NCs) have become important as suitable candidates for nano absorbents due to their simplicity and cheapness. This research investigated a nano absorbent based on starch nanocomposite containing hydroxyapatite (HA) and eggshell inspired by nature to absorb methylene blue (MB) as a toxic cationic dye from aqueous solution. The effect of temperature, pH, and the ratio of hydroxyapatite and eggshell absorbent on the amount of absorption after immersion in an aqueous medium was measured. The samples were identified by the UV-Vis spectrophotometer, scanning

28/09/2023This study focuses on the chemical analysis and prediction of Polyethylene Terephthalate (PET) toxicity, considering the influence of particle size and properties. The effect PET of different sizes (1, 4, 9, 16 and 25 nm coded NP1 to NP5) on aquatic organisms such as Terpedo californica (electric ray fish) and Danio rerio (zebrafish) as model species was evaluated by virtual chemical techniques and machine learning methodology based on Multilayer Perceptrons Artificial Neural Networks (MLP ANN) and Support Vector Machine. The PET NPs was built and characterized

28/09/2023The research deals with the manufacture of an electrode using modified carbon paste to determine 2,4-dinitrophenylhydrazine (2,4-DNPHZ), The modified carbon paste electrode (NiO-NCQD/g-C3N4/MCPE). The results show the presence of oxidation and reduction peaks, and it is subject to a quasi-reversible system; the best value of pH is (1) using sulfuric acid with a concentration of (0.1M), and scan rate is 100 mv sec-1, it was linearity range of (1-1000) µM for oxidation, and (100-1000) µM for reduction, with correlation coefficient

Adsorption of methylene blue dye onto bentonite clay: Characterization, adsorption isotherms, and thermodynamics s tudy by using UV-Vis technique
29/09/2023This study uses the UV-Vis technique to describe the elimination of methylene blue dye from an aqueous solution by adsorption on an Iraqi bentonite clay surface. The batch approach was used to conduct adsorption studies carried out to evaluate the influence of factors of experimental like contact time (0–90 min), clay dose (0.1–0.35 g), and initial dye concentration (10–125 mg L-1) at the range of temperatures (25-40oC). The Langmuir and the Freundlich isotherms were used to analyze the data; the Langmuir isotherm (R2 = 0.998) proved more appropriate for the
