در این مطالعه، عملکرد دو سیستم اکسیداسیون شیمیایی پیشرفته و یک سیستم بیولوژیکی برای حذف آموکسی سیلین در فاضلاب های سنتزیدر غلظت های مشابه با موارد صنعتی مورد بررسی قرار گرفته شدند. مطالعه انجام شده دارای سه بخش متفاوت اکسیداسیون با ازن و اشعه uv، اکسیداسیون با استفاده از نانو فتوکاتالیست tio2 و استفاده از بیوراکتور هوازی لجن فعال با جداکننده های فیزیکی می باشد. در هر بخش، متغیر های متفاوتی متنا...
15 صفحه اولScreening test for assessment of ultimate biodegradability: linear alkylbenzene sulfonates.
A relatively simple shake-flask system for determining CO2 evolution was developed to assess the ultimate biodegradability by soil and sewage micro-organisms of chemicals which enter the environment. Linear alkylbenzene sulfonates (LAS) were used as model compounds to evaluate the method and were found to undergo substantial biodegradation in this dilute system. At the 30 mg/liter test concentr...
متن کاملBiodegradation of linear alkylbenzene sulfonates in sulfate-leached soil mesocosms.
Aromatic sulfonates (R-SO(3)(-)) can be used as sulfur sources by sulfate-starved bacteria in laboratory cultures and the corresponding phenols are excreted from the cells. The present study was conducted to demonstrate whether such desulfonation reactions also occur in sulfate-leached agricultural soil, where desulfonation of organic sulfur compounds may have agronomic importance as a S source...
متن کاملDegradation of Atrazine by Advanced Oxidation Processes
Advanced oxidation processes like ozonation (O3) and ultrasonic irradiation (US) can be employed for the removal of recalcitrant compounds from water matrices. Atrazine is a pesticide which has been banned in the EU countries, since it is toxic and potentially carcinogenic even in very small concentrations. After their use in agricultural areas, the pesticides tend to leave residuals on the soi...
متن کاملEffects and risk assessment of linear alkylbenzene sulfonates in agricultural soil. 5. Probabilistic risk assessment of linear alkylbenzene sulfonates in sludge-amended soils.
Linear alkylbenzene sulfonates (LAS) can be found in high concentrations in sewage sludge and, hence, may enter the soil compartment as a result of sludge application. Here, LAS may pose a risk for soil-dwelling organisms. In the present probabilistic risk assessment, statistical extrapolation has been used to assess the risk of LAS to soil ecosystems. By use of a log-normal distribution model,...
