However, regarding to initial operating costs, ease of operation, simplicity of equipments design, adsorption onto activated carbon process has been found to be an efficient and economic process to remove dyes and other pollutant from wastewater (Annadurai and Lee 2002; Grégorio Crini 2010; Algidsawi 2011).
Small systems usually exploit fixed beds to benefit from the operation simplicity.
Some advantages of this procedure are operation simplicity, high yields, low reaction time, simple work-up, reusability and recyclability of magnetic nanocatalyst, avoidance of organic toxic solvents.
Compared with the various previously reported catalysts, the newly synthesized nanocatalyst is found to be most efficient with regard to operation simplicity, reaction time, yield and ease of catalyst separation.
Among these, biosorption has proved to be a potential alternative to these techniques due to its high efficiency, ease of operation, simplicity of design, and comparable low cost (Chowdhury and Saha 2010; Saha et al. 2010).
In conclusion, the preparation procedure follow in this work for synthesis of some nucleosides derivatives from L- rhamnose with expected biological activity show operation simplicity, cleaner reaction, easy work-up and improved yields.
So CO2 capturing and separation especially by adsorption is one of the most interesting approaches because of the low equipment cost, ease of operation, simplicity of design, and low energy consumption.
There are several methods used for the defluoridation of drinking water, of which adsorption processes are generally considered attractive because of their effectiveness, convenience, ease of operation, simplicity of design, and for economic and environmental reasons.
Given its design and operation simplicity, portability, blood cell sorting efficiency, and in situ cellular analysis capability, the CMC holds promise for blood-based diagnosis and disease monitoring in POC applications.
The advantages of ultrafast operation, simplicity, tunability, high contrast, stability of CuPc-doped PMMA thin film, and the possibility to control and realize various logic operations in the same film at the same wavelength by only controlling the pulse intensity, instead of a pump-probe configuration, make them attractive for practical implementation.
