The adsorption of methylene blue (MB) from aqueous solution by deionized-water functionalized activated carbon (DFAC) was investigated in a laboratory-scale batch mode. The interaction effects of different operating parameters; adsorbent dosage (1-5 g/L), pH (2-12) and agitation speed (100-200 rpm) were studied. The ANOVA results suggested the quadratic model and the analyzed model were well fitted. The higher correlation coefficient, R2 value of 0.93 and low p-value (0.0002) indicating the fitness of the response surface quadratic model developed. The optimum conditions were found to be the adsorbent dosage of 4.7 g/L, pH of 12 and agitation speed of 150 rpm, in which 99.74 of MB removal was achieved. Additionally, the confirmatory experiment was conducted to evaluate the accuracy of the optimized conditions in which the range of deviation is was 4.07. © 2020 Trans Tech Publications Ltd, Switzerland. date: 2020 publisher: Trans Tech Publications Ltd official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-85086895394&doi=10.4028%2fwww.scientific.net%2fKEM.841.220&partnerID=40&md5=62aeb0b55f1947f6a9acb4727bc7e22e id_number: 10.4028/www.scientific.net/KEM.841.220 full_text_status: none publication: Key Engineering Materials volume: 841 KE pagerange: 220-224 refereed: TRUE isbn: 9783035715149 issn: 10139826 citation: Saafie, N. and Samsudin, M.R. and Sufian, S.
