Abstract

In this work, several characteristics of microfluidic and bulk reactors, such as synthesis, activity, kinetics, and stability, have been compared. Synthesis aspects reveal that the microfluidic system is more successful in reducing the size distribution. Moreover, synthesis temperature and time have been decreased from above 100 °C to room temperature and from hours to minutes. Two superb properties of microfluidic system which assist the synthesis of nano-materials are the selective incorporation of nanoparticles (M4) and local heating (M5). The bio-photo-catalyst synthesized in microreactor M1 at 70 °C is capable of up amoxicillin (with a high concentration of 50 ppm) degradation with 100% efficiency. The kinetics data can show that the reaction rate in microfluidic system is more than 40 times of the bulk. The stability test showed that after five cycles of use, 95% and 70 of the efficiency over amoxicillin degradation has been kept in microfluidic (M5) and bulk systems, respectively.

期刊介绍: International Journal of Environmental Science and Technology (IJEST) is an international scholarly refereed research journal which aims to promote the theory and practice of environmental science and technology, innovation, engineering and management. A broad outline of the journal''s scope includes: peer reviewed original research articles, case and technical reports, reviews and analyses papers, short communications and notes to the editor, in interdisciplinary information on the practice and status of research in environmental science and technology, both natural and man made. The main aspects of research areas include, but are not exclusive to; environmental chemistry and biology, environments pollution control and abatement technology, transport and fate of pollutants in the environment, concentrations and dispersion of wastes in air, water, and soil, point and non-point sources pollution, heavy metals and organic compounds in the environment, atmospheric pollutants and trace gases, solid and hazardous waste management; soil biodegradation and bioremediation of contaminated sites; environmental impact assessment, industrial ecology, ecological and human risk assessment; improved energy management and auditing efficiency and environmental standards and criteria.
