Summary: The continuous adsorption of RBB dye onto CATRM in a fixed bed column was investigated. Different experimental conditions were tested, and the results showed that lower dye concentration, higher bed height, and lower influent flow rate favored the adsorption efficiency. The maximum adsorption capacity of the CATRM bed was 106 mg/g, and important parameters such as MTZ and LUB were evaluated from the breakthrough curves.

Summary: The current study investigated the effects of wheat straw aqueous extract on bermudagrass, a model of harmful weeds for the wheat crop. The extract significantly decreased germination percentage and index, and affected morphological growth parameters of bermudagrass seedlings. Analysis revealed the presence of phenolic acids and flavonoids in the extract. The highest extract concentrations resulted in a decrease in chlorophyll content and an increase in free amino acids, total protein, and soluble carbohydrates.

Summary: The dynamic performances of various adsorbents in removing lead ion, Pb(II), from aqueous solution in an industrial-sized packed bed column were investigated through numerical simulation. Among the different adsorbents, apricot stone activated carbon showed the highest adsorptive performance, suggesting a cheaper and environmental-friendly alternative. A simple analysis method was formulated for comparing the adsorptive performance using information from batch experiments.

Summary: This study develops a mathematical model for the erosion or leaching process of a solid material by a flowing fluid in a column. The model combines an advection-diffusion equation with a linear kinetic reaction to describe the mass transfer between the solid and fluid. Two specific cases are analyzed, and perturbation and numerical solutions are used to verify the model. The model is also validated using experimental data, showing excellent agreement in estimating the extracted fraction.

Summary: This study investigated the content of carotenoids and tocols in different genotypes of wheat species and found that Triticum durum had the highest carotenoid content, while Triticum dicoccum had a lower tocols content compared to other species. There were positive correlations between tocols and 13/gamma tocotrienols, and different genotypes from the same species were grouped into different clusters.

Summary: In the Indo-Gangetic Plains, wheat stubble burning during May results in the emission of soot, which acts as an ice nucleating particle and affects cloud properties. A heavy rainfall event in Rajasthan, India on 13 May 2020 was studied using ground- and satellite-data. The presence of black carbon (BC) derived from crop residue burning was found to dominate the fine aerosol, and its interaction with water vapor led to increased ice concentration in the clouds.

Summary: A population study was conducted on four colors of Pakistani ballpoint pen inks commonly used in the market. UV/Vis spectroscopy and FTIR spectroscopy were used to investigate and discriminate the ballpoint pen inks. The results were compared in terms of discriminating power (DP), and statistical techniques were applied for data analysis. The study found that green ballpoint pen inks had the highest DP when using UV/Vis and FTIR techniques. Black and red inks showed the highest DPs using UV/Vis spectroscopy, while blue ink achieved the highest DP using FTIR spectroscopy. Using chemometric techniques improved the DP and obtained higher DPs compared to visual examination.

Summary: Electrochemical sensors based on carbon paste electrodes modified with Zinc oxide (ZC) and Zinc Oxide-Copper-Benzene Tricarboxylic acid (ZBC) were fabricated for voltammetric estimation of toxic Cd (II) ions. The synthesized materials were characterized and mixed with appropriate amounts of graphite powder and paraffin oil to generate a variety of modified carbon paste electrodes. The optimized conditions for Cd(II) ions determination were determined using potentiostat workstation. ZBC showed better performance than ZC, with lower LOQ and LOD, larger surface area, and smaller electrode modifier amount.
