Colloids in the Environmental Protection—Current and Future Trends

摘要: Abstract This review highlights the current understanding of role colloids in environmental protection. There is a growing public interest developing risk assessment framework, environment regulations, and remedial strategies for protecting ecosystems humans from hazards. “Colloidal” attitude means that systems are made tiny building elements and, as consequence, have high specific surface area unique properties, different those exhibited by ordinary homogeneous or heterogeneous systems. One main properties their instability, due to free energy; stability requires special measures, usually done making an adequate boundary layer structure at interfaces. Colloid can be well classified internal morphology. many kinds stresses such heavy metals drinking water, pesticides, food contaminants. Colloids successfully applied areas A number energy technologies already benefited substantially colloidal technology. The present describes protection wastewater treatment, metal remediation, treatment contaminated soils, removal xenobiotics, abatement pesticide contamination soil, against radioactive materials, corrosion, use drug carriers, emulsions, microgels, reduced-waste improved efficiency, environmentally friendly composite structures, waste conversion. Special emphasis will placed on future trends involving stresses.
