Ultraviolet spectrophotometry has been successfully used for the qualitative as well quantitative determination of various phytoconstituents. For phytoconstituents in extract by ultraviolet spectrophotometry, absorbance at specific wavelength is measured. As a mixture number constituents, different constituents same along with compound interest can occur giving wrong interpretation observed dat...
In order to understand the cause of coloration of fluorites, following experiments (UV-spectroscopy, irradiation by gamma ray and thermal bleaching) carried out on the colored and colorless fluorites from the mines of Mazandaran Province. All colored and colorless fluorites have absorption band in UV part of electromagnetic waves but deep-violet and brown fluorites have an absorption band in vi...
In this paper, highly stable violet-blue emitting ZnSe/ZnS core/shell QDs have been synthesized by a novel "low temperature injection and high temperature growth" method. The resulting nearly monodisperse ZnSe/ZnS core/shell QDs exhibit excellent characteristics such as a high color saturation (typical spectral full width at half-maximum between 12 and 20 nm), good emission tunability in the vi...
INTRODUCTION Crystal violet was commonly used for the treatment of oral and vaginal candidiasis or for sterilization during operations up to the 1960s. Because crystal violet is potentially toxic to mucosal membranes, it has been replaced with other disinfectants, and crystal violet is rarely used. We report a case of chemical cystitis due to intravesical instillation of crystal violet dye. C...
Potatoes (Solanum tuberosum L.) are an essential food for the human diet and thus represent important source of biologically active substances. This study aimed at investigating content bioactive substances (total anthocyanin polyphenol contents chlorogenic acid) in seven potato varieties (Belana, Cecile, Magenta Love, Mozart, Talentine, Toscana, Violet Queen) with various flesh skin colors. To...
در این تحقیق پودر تفاله چای برای حذف رنگزای acid brill scarlet 3r (acid red 18) مورد بررسی قرار گرفته است. خصوصیات سطح تفاله چای با استفاده از semبررسی شد. اثر متغیرهای فرایند همچون مقدار جاذب، غلظت اولیه رنگ، ph، زمان و دما مطالعه شد. داده ها برای تطابق با مدل های ایزوترم لانگمویر، فروندلیچ، تمکین ودابینین - رادوشکوویچ ارزیابی شد. نتایج نشان داد که داده ها برای جذب سطحی acid red 18 برروی تفاله...
