Abstract:
In this work, the microwave synthesis of activated carbon material from cotton lint samples was developed and improved, with the priority task of determining the conditions and performance of ”full activation“ during microwave carbonization. Using such methods as optical and electron microscopy, X-ray microtomography, X-ray fluorescence analysis, X-ray phase analysis and evaluation on methylene blue adsorption, morphology, elemental and phase compositions, as well as adsorption capacity of carbonized cotton lint samples at different microwave exposure modes were investigated. It is experimentally shown that microwave activation can be carried out in a single step. It is assumed that a deeper degree of purification or the use of purer raw materials will allow to achieve higher adsorption capacity values.
