Microstructurally Engineered Ceramics for Environmental …

4 Conclusion
The MHNPL samples show the efficiency as high as 99.99% for the removal of
Cu(II) ions through adsorption. It occurs most likely by an ion-exchange mechanism. The DMHNPLA samples exhibit 98% efficacy for degradation of MB dye.
This occurs due to direct sunlight-induced photocatalytic activity that aids in generation of free hydroxyl radicals which degrade the cationic MB dye. These facts show
that microstructurally designed nanoceramic hydroxides, e.g., Mg(OH) 2 can be successfully used for futuristic environmental applications, e.g., treatment of industrial
wastewater containing toxic ions and dyes.
