Fourier transforms infrared spectro

Fourier transforms infrared spectroscopies (FTIR) (Bomem, MB 100) were carried out to identify the functional groups of the biochar. Scanning electron microscopy (Hitachi JSM-6700F SEM) was implemented to observe the surface microstructures of the biochar. The pH of the (BB) was measured by suspending the (BB) with demineralized water at a mass ratio of 1:20. The solution was then hand-stirred and allowed to stand for 5 (min) before measurement
A. Hassan et al. / EnvironmentAsia 9(1) (2016) 37-44 with a pH meter (Inyang et al., 2012). The (BB) surface potential was determined by measuring the zeta potential (ζ) of the colloidal biochar suspension obtained through sonication according to the procedure of Johnson et al. (1996). Charge mobility of each suspension was determined using Brookhaven Zeta Plus (Brookhaven Instruments, Holtsville, USA), and Smoluchowski’s formula was used to convert the electric mobility into zeta potential.

Fourier-transforms infrarooi Spectroscopie (FTIR) (Bomem, MB 100) is uitgevoer om die funksionele groepe van die biochar identifiseer. Skandeerelektronmikroskopie (Hitachi JSM-6700F SEM) is geïmplementeer om die oppervlak mikrostrukture van die biochar waarneem. Die pH van die (BB) is gemeet deur die opskorting van die (BB) met demineralized water by 'n massa verhouding van 01:20. Die oplossing was dan geroer en toegelaat vir Hand-5 (min) te staan voor meting
A. Hassan et al. / EnvironmentAsia 9 (1) (2016) 37-44 met 'n pH meter (Inyang et al., 2012). Die (BB) oppervlak potensiaal is bepaal deur die meting van die zeta potensiaal (ζ) van die kolloïdale biochar skorsing verkry deur sonication volgens die prosedure van Johnson et al. (1996). Beheer mobiliteit van elke suspensie is bepaal deur gebruik te Brookhaven Zeta Plus (Brookhaven instrumente, Holt Ville, VSA), en Smoluchowski se formule is gebruik om die elektriese mobiliteit te omskep in zeta potensiaal.
