“…Into the six glass beaker (50 mL capacity), the 20 mL of RBB 15 ppm solution and 0.075 g of IW-AC was added. The mixture was then shaken at 250 rpm for desired initial RBB concentration (10,20,30,40,60,80, and 100 ppm). The mixture was then filtered, and the filtrate was analyzed with a UV-Vis spectrophotometer at a wavelength of 632 nm for each treatment.…”

Synthesis of activated carbon (AC) from green, low-price, and renewable source as a pollutant adsorbent is growing interest of researcher. This work aims to synthesis of AC from Ilalang weed (<em>Imperata cylindrica</em>) (IW-AC) with KOH activator as a green and low price Remazol Brilliant Blue dye (RBB) adsorbent. The success IW-AC synthesis was evidently characterized by Fourier Transform-Infrared (FT-IR) and Scanning Electron Microscopy (SEM). The effects of initial solution pH, adsorbent dosage, initial RBB concentration, and contact time were systematically investigated. Results showed the optimum condition of RBB adsorption was occurred at low pH (2.0-4.0) and 75 mg of adsorbent dosage. Under the optimum condition, the equilibrium adsorption data fitted well to the Langmuir isotherm with the adsorption capacity of RBB uptake was 13.42 mg/g. Calculation of adsorption energy by Dubinin-Radushkevich (D-R) isotherm model (13.39 kJ/mol) showed that the electrostatic interaction was the main interaction of RBB adsorption on IW-AC. Adsorption kinetics showed that the adsorption behavior followed the Ho pseudo-second-order kinetic model. The experimental results of this work demonstrate that the IW-AC can be used as a promising green and low-cost adsorbent for removal of anionic dyes from aqueous solution.

Uji adsorpsi methylene blue dengan asam humat teresterifikasi dilakukan dengan variasi pH 1, 3, 5 dan 7. Hasil adsorpsi optimum diperoleh menggunakan rasio pelarut ekstraksi kloroform : air (1:1) dengan persen penyisihan 99,86% dan kapasitas adsorpsi maksimum sebesar 454,54 mg/g pada pH 5. Adsorpsi methylene blue menggunakan adsorben asam humat tereserifikasi terjadi secara fisisorpsi dengan nilai konstanta kesetimbangan sebesar 0,3666 L/mg yang mengikuti pola isoterm adsorpsi Langmuir mengasumsikan bahwa adsorpsi terjadi secara monolayer dimana hanya terdapat satu lapisan molekul pada permukaan adsorben yang diserap.
