Application of this procedure with the use of a portable UV spectrophotometer was carried out to study treated wastewater discharge into a river. The data obtained were used to estimate dilution factors of polluted waters at different points of sampling. This simple and rapid methodology can be ...

AIllustration of visualizing eYGFPuv-expressing samples using UV light. Under long-wavelength UV light (365 nm), eYGFPuv-expressing leaves show green fluorescence, while non-transformed leaves show red autofluorescence.BVisualization of eYGFPuv in leaf under UV light, three days post tobacco (N....
紫外可見光譜是一種科學技術,用於測量樣品在不同波長的紫外線 (UV) 和可見光 (Vis) 下吸收或透射的光量。 該過程包括用紫外線可見光光束照射樣品並測量穿過樣品的光量。透過分析光的吸收和透射模式,科學家可以識別和量化樣品的成分。 當物質在特定波長吸收最大光時,物質與其紫外線可見光譜之間存在獨特的關係...
Since the number of multidrug regimens being administered is increasing, separation techniques, such as LC need to be used instead of a UV-Vis spectrophotometer (Greco and Vicent, 2009; Gumustas et al., 2013, 2014a; Kilicarslan et al., 2014; Tucker et al., 2012). Gumustas et al....
UV-Vis spectroscopy was performed on a LAMBDA™ 750 UV/Vis/NIR spectrophotometer (PerkinElmer) equipped with a 150 mm integrating sphere. Sample films with a thickness of 6 um were illuminated with 365 nm LED (Mouser Electronics) between measurements with intensity ~ 50 mW/cm2and 1–5...
The concentration of dyes, such as Orange G (OG) and malachite green (MG), was determined by a UV–vis spectrophotometer (UVmini-1240, Shimadzu, Japan) under wavelengths of 504 nm and 617 nm, respectively. The degradation intermediates were detected and identified by HPLC (1260 Infinity ...
A uv-visible recording spectrophotometer has been developed which uses an on-line general purpose digital computer and the optical train of a conventional ... RJ Desa,JE Wampler - 《Applied Spectroscopy》 被引量: 4发表: 1973年 Visible Quantitative Methods for the Estimation of Furosemide in Pure...
of Recent EMF Treatment Studies“. Similarly, Kney and Parsons47used UV–Vis spectrophotometer to measure the absorbance of the tested solution. Peak absorbance appeared when the maximum number and size of particles was reached, after that a decrease was observed owing to sedimentation and/or ...
A blank was also prepared that contains 1 ml of distilled water instead of enzyme. The mixture was incubated at 30 °C for 15 min and the absorbance was read at 450 nm using UV spectrophotometer. Enzyme activity was expressed as International Units (IU), where 1 IU is the amount of enzy...
