Effective aqueous chromate treatment using triethanolamine anacardate coated magnetic nanoparticles.

Low-cost adsorbents derived from agricultural by-products incorporated magnetic nanoparticles (NPs) are promising for wastewater treatment. They are always preferred due to their great performance and easy separation. This study reports cobalt superparamagnetic (CoFeO) nanoparticles (NPs) incorporated with triethanolamine (TEA) based surfactants from cashew nut shell liquid, namely TEA-CoFeO, for the removal of chromium (VI) ions from aqueous solutions.
