Abstract
The existence of organic pollutants such as dyes and antibiotics in water poses serious health risks. The use of oxygen plasma to functionalize and apply oxygen containing functional groups onto surfaces can convert them to precious and useful adsorbents. In this work, functionalization of the inner layer of the disposable masks was performed via oxygen plasma treatment and the prepared catalyst applied for the removal of methylene blue and metronidazole from aqueous systems. Oxygen plasma treated masks (PTM) were identified via the contact angle measurement and the best sample was further functionalized with aminopropyl trimethoxysilane linked to L-Arginine. The synthesized PTM-APTMS-L-arginine composite was fully analyzed by various characterization techniques including XRD, BET, TGA, and FeSEM. The FTIR and EDS analysis showed that L-arginine is well distributed in a Polypropylene matrix. Moreover, the adsorption model was in good agreement with the Langmuir model with an adsorption capacity of 254 mg/g and 1006 mg/g for MNZ and MB respectively. Kinetics data were described well by pseudo-second-order for both pollutants. The results introduced the synthesized composite as a promising candidate for the water treatment process.
期刊介绍:
Polymer Testing focuses on the testing, analysis and characterization of polymer materials, including both synthetic and natural or biobased polymers. Novel testing methods and the testing of novel polymeric materials in bulk, solution and dispersion is covered. In addition, we welcome the submission of the testing of polymeric materials for a wide range of applications and industrial products as well as nanoscale characterization.
The scope includes but is not limited to the following main topics:
Novel testing methods and Chemical analysis
• mechanical, thermal, electrical, chemical, imaging, spectroscopy, scattering and rheology
Physical properties and behaviour of novel polymer systems
• nanoscale properties, morphology, transport properties
Degradation and recycling of polymeric materials when combined with novel testing or characterization methods
• degradation, biodegradation, ageing and fire retardancy
Modelling and Simulation work will be only considered when it is linked to new or previously published experimental results.
