Summary: A new nanocomposite, A-CNF/DT, was successfully synthesized and used for the removal of methylene blue and indigo carmine dyes from water. Langmuir and Sips isotherm models well fitted the adsorption isotherm data of methylene blue and indigo carmine onto A-CNT/DT, respectively. The experimental kinetic data showed good agreement with pseudo-first order model (for the adsorption of methylene blue) and pseudo-second order model (for the adsorption of indigo carmine) onto A-CNT/DT. Thermodynamic parameters indicated that the adsorption of methylene blue was endothermic, while the adsorption of indigo carmine was exothermic. Monte-Carlo calculation method revealed both polar and nonpolar interactions between the dye molecules and the A-CNT/DT surface. Overall, the synthesized A-CNT/DT proved to be an efficient adsorbent for the removal of dyes from aqueous solutions.

Summary: CMC@Fe3O4 composite, a magnetic biological molecule, was synthesized and used as an adsorbent to remove cationic dyes from aqueous solutions. Various techniques were used to characterize the adsorbent, including FTIR, FESEM, XRD, VSM, and TGA. The adsorption process was influenced by factors such as pH, temperature, contact time, adsorbent concentration, and initial dye dosage. The synthesized adsorbent showed spherical shapes and different sizes. The adsorption capacity of the dyes was determined, and the adsorption processes were found to be exothermic reactions. The regeneration and reusability of the adsorbent were also evaluated.

Summary: Water pollution is a severe issue caused by industrial growth and urbanization. Heavy metals, a contaminant of widespread concern, accumulate in the environment due to both natural and human activities. Adsorption is the most commonly used method for heavy metal removal due to its simplicity, speed, and cost-effectiveness. In this study, a CuCl2-modified metal-organic framework (MOF-5) was used as an adsorbent to simultaneously remove lead and cadmium ions. The structure was characterized using various techniques, and the optimum adsorption conditions were determined using central composite design.

Summary: This paper describes the development of a low-cost yet efficient PEDD-based photometer. It utilizes a white LED as the emitter diode, an RGB LED as the detector diode (a novelty), and a multimeter for signal recording. The photometer was used to detect 2,4,6-trinitrotoluene (TNT) in soil samples by using a Meisenheimer complex of TNT with NaOH in acetonitrile as a probe. The method showed a linear calibration curve in the concentration range of 0.86 to 110 μg g(-1), with a detection limit of 0.27 μg g(-1) and a quantification limit of 0.81 μg g(-1). Analysis of soil samples from Iran Cinema and Television Town revealed trace residues of TNT.
