Abstract
Pulsed underwater direct current discharge is considered as a tool for a one-step process for ferrite synthesis and organic dye removal. The formation of cobalt, nickel and titanium ferrites during the discharge firing process was confirmed by methods of dynamic light scattering and X-ray phase analysis. The transformation of dye molecules (fluorescein, methylene green) during the combined action of plasma and ferrites was detected by UV absorption spectroscopy. The contributions of the separate action of plasma and ferrites to the process of dye removal from the solution were investigated. It was found that the synthesized structures have a high sorption capacity. It was found that fluorescein can be used as an indicator for the presence of nickel ferrites.
脉冲水下直流放电被认为是一步法合成铁氧体和去除有机染料的工具。动态光散射和 X 射线相分析方法证实了放电烧制过程中钴、镍和钛铁氧体的形成。在等离子体和铁氧体的共同作用下,染料分子(荧光素、亚甲基绿)的转化是通过紫外吸收光谱法检测的。研究了等离子体和铁氧体的单独作用对从溶液中去除染料过程的贡献。结果发现,合成的结构具有很高的吸附能力。研究还发现荧光素可用作镍铁氧体存在的指示剂。
期刊介绍:
Publishing original papers on fundamental and applied research in plasma chemistry and plasma processing, the scope of this journal includes processing plasmas ranging from non-thermal plasmas to thermal plasmas, and fundamental plasma studies as well as studies of specific plasma applications. Such applications include but are not limited to plasma catalysis, environmental processing including treatment of liquids and gases, biological applications of plasmas including plasma medicine and agriculture, surface modification and deposition, powder and nanostructure synthesis, energy applications including plasma combustion and reforming, resource recovery, coupling of plasmas and electrochemistry, and plasma etching. Studies of chemical kinetics in plasmas, and the interactions of plasmas with surfaces are also solicited. It is essential that submissions include substantial consideration of the role of the plasma, for example, the relevant plasma chemistry, plasma physics or plasma–surface interactions; manuscripts that consider solely the properties of materials or substances processed using a plasma are not within the journal’s scope.
