The environmental pollution caused by drug antibiotic waste presents a foremost concern in the ecosystem,as high levels of these antibiotic drugs after consumption when released into the ecosystem, biologicalsamples are accumulated and are producing overall contamination. Consequently, the need for selective,sensitive, fast, easy-to-handle, and low-cost early monitoring detection systems is growing. In this study, weused a prepared Albizia Lebbeck Leaves-capped AgNPs sensor to illustrate examples of friendly biosensorswith their real application fields for the sensitive detection of the metronidazole drug in various matricessuch as human fluids by kinetic spectrophotometric method. The calibration curve was linear in the range of(0.02 to 10.0 µg L−1). The standard deviation of less than (3%), and detection limits (3S/m) of the method(0.02 µg L−1in time 8 min, 367 nm) were obtained for sensor level response Albizia Lebbeck Leaves-cappedAgNPs with (95%) confidence evaluated. The artificial neural network model was used as a tool very low fordetermining mean square error (MSE 0.061) for metronidazole drug by Albizia Lebbeck Leaves-cappedAgNPs sensor. The observed outcomes confirmed the suitability of recovery and a very low detection limitfor measuring the metronidazole drug. The method introduced to measure metronidazole drugs in realsamples such as urine and blood was used and can be used for other drugs environmental pollution andhospital samples. تفاصيل المقالة

The applicability of Albizia Stem Bark Lebbeck Modified by Fe2 (MoO4)3 nanocomposite synthesis for removing Rhodamine B dye from aqueous solutions has been reported. Identical techniques including BET, IR, XRD, EDX, and SEM have been utilized to characterize this novel material. Also, the impacts of variables including initial Rhodamine B dye concentration (X1), pH (X2), adsorbent dosage (X3), and Sonication time (X4) came under scrutiny using central composite design (CCD) under response surface methodology (RSM).The values of 10 mg L-1, 0.025g, 6.0, 5.0 min were considered as the ideal values for Rhodamine B dye concentration, adsorbent mass, pH value, and contact time respectively. The adsorption equilibrium and kinetic data were fitted with the Langmuir isotherm model and pseudo-second-order kinetics (R2: 0.999) with maximum adsorption capacity (qmax: 98.0 mgg-1) respectively. Thermodynamic parameters (R2: 0.998, ΔG°: -95.58 kJ mol-1, ΔH°: -29.24 kJ mol-1, ΔS°: -131.49 kJ mol-1 K-1) also indicated Rhodamine B dye adsorption is feasible, spontaneous and exothermic. The overall results confirmed that Albizia Stem Bark Lebbeck Modified by Fe2 (MoO4)3 nanocomposite could be a promising adsorbent material for Rhodamine B dye removal from aqueous solutions. تفاصيل المقالة

Fluorescent chemical sensors to detect drugs, by increasing fluorescence emission and absorption or by shutting down, because they are non-destructive, the ability to show decomposed concentrations, fast response, high accuracy have been considered and used. In this research, a chemical sensor was synthesized PbS functionalized with gelatin quantum dots for Phenylpropanolamine (PPA) drug. The calibration curve was linear in the range of (0.05 to 10.0 µgL−1). The standard deviation of less than (2.0 %), and detection limits (3S/m) of the method (0.05 µgL−1) in time 60 s, 335 nm were obtained for sensor level response PbS Quantum Dot–Gelatin nanocomposites sensor with (99 %), confidence evaluated. The observed outcomes confirmed the suitability recovery and a very low detection limit for measuring the Phenylpropanolamine drug.

The chemical PbS Quantum Dot–Gelatin nanocomposites sensor made it possible as an excellent sensor with good reproducibility. تفاصيل المقالة

The applicability of CM-β-CD-Fe3O4NPs synthesis for the removal of Aluminum ion from wastewater was studied. The active sites and morphology structure of CM-β-CD-Fe3O4NPs synthesis were analyzed using BET, FT-IR, XRD, SEM, and XPS respectively. The effect of independent variables namely pH, adsorbent dosage, contact time, Al (III) ion concentration in solution, were investigated through batch experiments, and to be 7, 50 mg L-1, 0.1 g and 90 min for the adsorption of Al (III) ion onto CM-β-CD-Fe3O4NPs sorbent were found respectively. The adsorbed Al (III) ion onto the CM-β-CD-Fe3O4NPs showed excellent fitting to the pseudo-first-order adsorption kinetic with a correlation coefficient value of 0.999.Meanwhile, the experimental equilibrium data were fitted to the conventional isotherm models accordingly.
