Microstructurally Engineered Ceramics
for Environmental Applications
Pradip Sekhar Das, Shruti Kakkar and Anoop Kumar Mukhopadhyay
Abstract This chapter focusses on how the microstructurally engineered ceramics can be successfully used for environmental applications, e.g., in development of
materials that can be used for treatment of industrial wastewater. Industrial wastewater comes from mainly iron and steel industries, textile, and leather industries, as
well as paper and pulp industries. Other contributors to this scenario are non-ferrous
metals, chemicals, mining, petrochemicals, and refineries. Microelectronics as well
as the pharmaceutical industries also contribute. It is well known that industrial
wastewater contains toxic ions and dyes. When such contents cross the permissible
limit it may become an issue of major environmental concern. The present work
demonstrates that by using the microstructurally designed, phase pure Mg(OH) 2
nanoplatelets 99.99% adsorption of the toxic Cu(II) ion can be achieved. Further, it
is shown that phase pure micro-dumbbell shaped three dimensional, self-assembly
of Mg(OH) 2 nanoplatelets can degrade MB dye with 98% efficacy. The mechanisms
behind such extraordinary capabilities of engineered nanoceramics are discussed.
The implications of such developments for futuristic industrial wastewater treatment
is also focused on.
