In situSolution Plasma SynthesisofAmine-Terminated Silane-Modified Carbon Nanoparticles for Efficient Removal of Heavy Metal Ions

摘要

In recent years, the presence of heavy metal ions in groundwater and seawater systems has been attracted much attention due to their adverse effects on public health and ecological systems. Therefore, it is necessary to develop various efficient materialsfor removal of heavy metal ions contaminant. Carbon material is the most extensively used in this purpose based on itsinexpensive, high specific surface area, minimal costs, fastwatertransport, as well as its reusability. Nowadays, the researches focused on the development of carbon adsorbents with enhanced adsorption capacity. According to the previous work, it is well−known that the creation of functional group on carbon materials such as amine groups could be used as active site which expectedto enhance the removal of metal ions from aqueous solution. However, these conventional modification methods lead to a complicated solution, high cost, high toxic reagent as well as long time. Solution plasma process is one of the promising techniques which has been applied for the synthesis of carbonaceous materials. This process offers several advantages, for example, simple experimental system, inexpensiveness, short-time operation, and processing at room temperature and atmospheric pressure.
