The Removal of an anionic Reactive Blue 2 (RB2) dye in an aqueous solution was successfully achieved using a plasma-modified agricultural biomaterial waste. Sawdust from Moabi (Baillonellatoxisperma) and Sapelli (Entandrophragmacylindricum) was modified using non-thermal gliding arc plasma. The natural raw materials and plasma treated were characterized by Infrared Spectroscopy (FTIR), Thermogravimetric Analysis (TGA), Scanning Electron Microscopy (SEM), XRD, Chemical analysis by Fluorescence, Sorption Analyser, and Zetametry. Experimental parameters such as initial pH, contact time, adsorbent dose, initial RB2 concentration, and temperature were optimized. The results showed that the removal of Reactive Blue 2 dye was favorable at acidic pH conditions with the maximum capacity going from 172,85 to 200,91 mg.g-1 to 98,19 and 149,02 mg.g-1 respectively for raw and plasma-treated Sapeli and Moabi. The Avrami fractional-order kinetic provided the best fit to the experiments data and the thermodynamic adsorption data of untreated (SSB and SMB) and plasma-treated (SSM and SMM) sawdust followed an exothermic process. This work demonstrated that non-thermal plasma modified wood sawdust can be a good alternative absorbent for the removal of dye pollutants from an aqueous solution.

“…These gases are ionized into a plasma reactor, forming highly reactive species that depending on the conditions of the plasma are grafted to a greater or lesser extent changing the surface chemistry of the NPs. As in the surface modification of polymers, oxygen plasma is also used to graft polar groups onto the surface of the NPs (e.g., hydroxyl, carbonyl, carboxyl) and improve their wettability [105][106][107], although noble gases such as Ar can also be used to activate the surface of the particles or generate vacancies or defects and then at a later stage (or combination of gases) chemical groups are grafted either by plasma or by traditional wet chemistry methods [108]. NPs that have been modified by plasma include carbon nanotubes (CNTs), carbon nanofibers (CNFs), graphite [109], graphite oxide, nanoclays [110], and metallic and non-metallic NPs [111,112].…”

“…Plasma treatment is one of prospective ways of polymer's modification. [103][104] Plasmochemical treatment of polymers can be divided conditionally into two types: "dry" is treatment by low-temperature gaseous plasma and "wet" is treatment by plasma in solution systems. Interaction of plasma with polymer is complex multistep process proceeding various directions.…”

The work reports catalytic properties of series of cobalt phthalocyanines peripherally substituted with consistently changing sulfonated fragments. Data on heterogenization of cobalt phthalocyaninates onto organic and inorganic polymers are provided. Comparing catalytic activity of the macrocycles in dependence on structure and peripheral substituent as well as polymer carrier's type is given. Application of cobalt phthalocyanine's sulfonic acids for fine synthesis of thiuram E upon both homogeneous and heterogeneous catalysis is shown to be prospective.
