WitrynaThe first published papers [2-4] on organoclays provided details on the use of polar activators to promote exfoliation of organoclays in nonpolar solvents like toluene. In retrospect, it is fair to say that the most effective activators were low-molecular-weight molecules that happen to possess both a high dipole moment Witryna23 sty 2012 · Thus, bioreactive organoclays are prepared. The authors present a critical review of the scientific principles and scope of integrating microorganisms with organoclays to develop a new environmental friendly, risk–based, and cost-effective remediation technology. Furthermore, they propose new research directions in the field.

Bioreactive Organoclay: A New Technology for Environmental Remediation

Organoclay is an organically modified phyllosilicate, derived from a naturally occurring clay mineral. By exchanging the original interlayer cations for organocations (typically quaternary alkylammonium ions) an organophilic surface is generated, consisting of covalently linked organic moieties. The lamellar structure remains analogous to the parent phyllosilicate. Separation of the layers due to ion exchange, from the initial interlayer spacing of as little as 3 … Witryna3 lis 2024 · Organoclays have be noted to remove seven (7) times or more than its dry weight in oil making it more efficient than activated carbon. In this review, the researcher focused mainly on studies in which organoclays have been most effective. It is visually noted that the drains near fast food outlets have been observed to always contain oil ... my growing smile
