The need to reduce pollution and the waste of energy and resources imposes a wider diffusion of environmentally friendly membrane systems. The expanding domain of membrane operations demands tailored materials with unprecedented performances and resistance to temperature, chemicals and solvents, at affordable costs. Today, new polymeric, inorganic and hybrid materials are specifically engineered for the preparation of advanced membranes for industrial applications. This e-book gives readers an overview of the state-of-the-art materials science of synthetic membranes. Membranes for natural gas treatment, separation of organics, fuel cells, high and low temperature catalytic membrane reactors are some of the subjects covered by this volume. This e-book will be of interest to specialists in membrane science and technology, as well as for graduate students and researchers in chemical engineering, chemistry and materials science, both in the industry and in the academy.

Adsorption technology is a promising avenue for wastewater treatment. Numerous adsorbent materials are presently synthesized. Green or environmental friendly adsorbents are derived from plants and agricultural crop sources, giving them a very low production cost when compared to synthetic polymers. This monograph explains the basic principles of green adsorption technology, their production processes and strategies to remove different categories of environmental pollutants (dyes, heavy metals and phenols/pesticides). The book explains details in terms of features such as adsorption capacity, physico-chemical kinetics and reuse potential. A summary of the economics and future prospect for green adsorption technology is also given. This text is a handy reference for environmental chemistry students, researchers and policy makers.
