Microwave-Alkali Activation on the Morphology and Structure of Bamboo Activated Carbon

Abstract

A study was conducted for production of activated carbon (AC) from industrial bamboo waste using carbonization and Microwave-alkali (Mw-A) activation techniques. The aim of the study is to produce activated carbon with higher surface area via Mw-A activation techniques. The study was focused on the effect of activation (KOH soaking and Mw-A) and carbonization temperature (400oC and 500oC) on the physical and chemical structure of AC. The analysis was conducted using proximate analysis, BET surface area, FESEM and FTIR analysis. The morphology and characteristic study on activated carbon shown that Mw-A activation techniques gave higher BET surface area and well develop pore structure. The results indicated that Mw-A activation of activated carbon gave BET surface area of 950m2g-1, whereas by using steam activation only 719 m2g-1 of BET surface area was recorded. Higher carbonization temperature for Mw-A treated bamboo produced higher surface area of AC. At 500oC, 1578m2g-1 BET surface area of AC was achieved. This work highlighted, Mw-A activation can be applied and further enhanced to obtain higher surface area of activated carbon derived from industrial bamboo waste.

“…В работе [7] показано, что при температурах карбонизации бамбука 600 0 С и выше какая-либо тонкая структура ИК-спектров пропадает и сами спектры становятся малоинформативными. Однако, если химическую активацию бамбука проводить в условиях нагрева до 500 0 С, то в этом случае ИК-спектры хорошо характеризуют функциональные группы поверхности полученного материала [10]. Изменения в ИК-спектрах, происходящие при превращении бамбука в угольсырец и затем в активированный уголь наглядно представлены в публикации [7]…”

“…Having defined surface body area (m2 )due to Dubua monogram we have clarified heart index. Also, according to the formula minute blood volume(MBV), general peripheral vessel resistance(GPVR), miocarda mass of the left ventricular was defined.Doppler-electrocardiography was realized in impulse regime due to standard method [8,9,10]. Maximal speed of early and atria filling were clarified and calculated.…”
