Abstrak-Analisis besi(II) dengan pengompleks 1,10-fenantrolin pada pH 4,5 yang diganggu dengan penambahan campuran ion Cu 2+ dan Ni 2+ menggunakan spektrofotometer UV-Vis telah berhasil dipelajari. Pada penentuan panjang gelombang maksimum kompleks Fe(II)-fenantrolin diperoleh panjang gelombang maksimum sebesar 510 nm. Sedangkan kompleks Cu(II)-fenantrolin menyerap sinar pada panjang gelombang maksimum 315 nm dan kompleks Ni(II)-fenantrolin pada panjang gelombang maksimum 330 nm. Pada penentuan kurva kalibrasi diperoleh persamaan regresi linear yaitu y = 0,1248x + 0,013 dengan nilai koefisien korelasi (r) adalah 0,9990 dan koefisien determinasi (r 2) adalah 0,9982. Penambahan campuran ion Cu 2+ dan Ni 2+ mengakibatkan adanya kenaikan nilai absorbansi pada kompleks Fe(II)-fenantrolin. Campuran ion Cu 2+ dan Ni 2+ mulai mengganggu pada konsentrasi Cu 2+ 0,4 ppm dan konsentrasi Ni 2+ 0,6 ppm. Nilai % recovery pada variasi konsentrasi Cu 2+ dan Ni 2+ yaitu 120,4594 %, standar deviasi (RSD) sebesar 0,7550 ppt, dan koevisie n variasi (CV) sebesar 0,0755%.

“…Te natural deposits and refning of iron ores and industrial wastes are essential parameters for the existence of iron in natural water such as rivers, lakes, and groundwater. Te iron level in groundwater can be increased by the dissolution of iron compounds in soils or ferrous boreholes and handpump components through leaching from home water drinking, cooking, washing, cleaning, and agricultural purposes [1,2]. Generally, iron exists in natural fresh waters in the range of 0.5 to 50 mg L −1 .…”

The miniaturization of analytical systems and the utilization of nontoxic natural extract from plants play significant roles for green analytical chemistry methodology. In this work, the microfluidic hydrodynamic sequential injection (HSI) with the LED-phototransistor colorimetric detection system has been proposed to create an ecofriendly and low-cost miniaturized analytical system for online determination of iron in water samples using Curcuma putii Maknoi & Jenjitt. extracts as high stability and good selectivity of a natural reagent. The proposed method was designed for online solution mixing and colorimetric detection on a microfluidic platform. The Curcuma putii Maknoi & Jenjitt. extracts and standard/samples were sequentially aspirated to fill the channel before entering the built-in flow cell. The intensity of iron-Curcuma putii Maknoi & Jenjitt. extract complex was monitored under the optimum conditions of flow rate, sample volume, mixing zone length, and aspiration sequences, by altering the gain control of the colorimetric detector to achieve good sensitivity. The results demonstrated a good performance of the green analytical systems. A linear calibration graph in the range of 0.5–6.0 mg L−1 was obtained with a limit of detection at an adequate level of 0.11 mg L−1 for water samples with a sample throughput of 30 h−1. The precise and accurate measurement results were achieved with relative standard deviations in the range of 1.61–1.72%, and percent recoveries were found in the range of 90.6–113.4. The proposed method offers cost-effective, easy operation over an appropriate analysis time (2 min/injection) with good sensitivity and is environmentally friendly with low consumption of solutions and the use of high stability and good selectivity of nontoxic reagents. The achieved method was demonstrated to be a good choice for routine analysis.

“…Norfloxacin is a synthetic chemotherapeutic antibacterial agent occasionally used to treat common as well as complicated urinary tract infections [1]. Today, the sterilization method with radiation is often used in order to improve hygienic quality of the food, drugs and pharmaceutical raw materials, disposable medical products as well as to prolong their shelf lives and prevent food borne diseases [2][3].…”

In this study, Electron Paramagnetic Resonance (EPR) spectra of unirradiated and γ-irradiated at doses of 1, 5, 10, 12 and 15 kGy norfloxacin (NOF) were investigated. Before irradiation no EPR signal were observed. After irradiation a weak singlet signal at g = 2.0039 were obtained at room temperature. In order to describe the variation of EPR signal intensity with absorbed radiation dose, several mathematical equations were tried. Increasing irradiation dose up to 15 kGy has increased the signal intensity of the central signal however, no significant changes were observed in g spectroscopic splitting factor. The stability of signal intensity of irradiated NOF was studied over a storage period of 200 days. According to analyses conducted, EPR spectroscopy can be used to distinguish irradiated and unirradiated samples from each other.
