chemical recycling of polycarbonate waste using conventional heating and microwave assisted method
پلی کربنات یکی از پلاستیکهای مهمی است که به صورت گسترده در تولید لوحهای فشرده، قطعات رایانه، مواد ساختمانی و غیره مورد استفاده قرار می گیرد. این پلیمر بصورت عمده از تراکم مونومر بیس فنولa (bpa) و کربنیل کلرید یا دی متیل کربنات ها بدست می آید. در سالهای اخیر بازیافت شیمیایی پلی کربنات بیشتر مورد توجه بوده است. بازیافت شیمیایی پلی کربنات برای بدست آوردن مواد اولیه آن با روشهای متفاوتی مانند تجزی...
[Determination of chemical oxygen demand in water using near infrared transmission and UV absorbance method].
Chemical oxygen demand (COD) is a synthetical indicator which represents the degree of organic pollution in water. The near-infrared (NIR) transmission and the UV absorbance method based on photoelectric detection technology and spectroscopy analysis have some advantages such as high precision, speed, non-contact, no secondary pollution etc compared to conventional wet chemical method. The NIR ...
متن کاملEstimation of Chemical Oxygen Demand in WasteWater using UV-VIS Spectroscopy
The aim of this research is to build a portable system to perform real-time analysis of waste water samples. Thus, that can significantly improve existing waste water treatment technology. In waste water treatment plant, an important parameter, chemical oxygen demand is needed to be measured. The amount of chemical oxygen demand determines the degree of water pollution by organic material. The ...
متن کاملMethod development and validation of potent pyrimidine derivative by UV-VIS spectrophotometer
BACKGROUND A rapid and sensitive ultraviolet-visible (UV-VIS) spectroscopic method was developed for the estimation of pyrimidine derivative 6-Bromo-3-(6-(2,6-dichlorophenyl)-2-(morpolinomethylamino) pyrimidine4-yl) -2H-chromen-2-one (BT10M) in bulk form. RESULTS Pyrimidine derivative was monitored at 275 nm with UV detection, and there is no interference of diluents at 275 nm. The method was...
متن کاملMethod Development and Validation of Metronidazole Using UV Spectrophotometer
Metronidazole in METRONIDAZOLE I.V. Infusion 500mg/100ml was determined by Spectrophotometric method. Being a very simple, reliable and sensitive method was developed and adopted to perform the analysis of METRONIDAZOLE I.V. Infusion 500mg/100ml. The Spectrophotometric method described was found to be simple, sensitive and accurate. Therefore this could be applied for the determination of METRO...
