“…Centrifuge (One Med 0805-I) was used to separate the supernatant from the solid at each analysis interval (15 minutes). The absorbance was measured using a UV-Vis spectrophotometer at 665 nm for methylene blue [2]. Degradation methylen blue was estimated based on Eq.…”

“…The development of the nanoparticle synthesis method as a photocatalyst has attracted the interest of many researchers in overcoming the problem of waste generated from the production process of an industry, especially the textile industry [1]. The dyes commonly used in the textile industry are generally made from compounds containing benzene groups such as methylene blue (C16H18ClN3S) which is a non-biodegradable organic pollutant, because there is a benzene group that is difficult to degrade [2]. When methylene blue in high concentrations pollutes the environment, it can cause adverse health symptoms, physiological reactions, and even physiological toxicity (pliers).…”

It is well known that adding the appropriate amount of Ag to semiconductor materials can enhance photocatalytic performance. In our previous study, the addition of Ag nanoparticles to ZnO enhanced the photocatalytic activity. The best photocatalytic performance was obtained when Ag content was 5 wt%. However, the effect of a carrier gas flow rate has not been investigated. The objective of this study is to investigate the effect of carrier gas flow rate on the morphology of the ZnO-Ag nanocomposites as well as the photocatalytic activity of the produced nanocomposites. ZnO-Ag nanocomposite was fabricated by a one-step process using flame pyrolysis and the produced nanocomposites were characterized by a scanning electron microscope (SEM) and X-Ray Diffraction (XRD) analysis. The photocatalytic performance was evaluated by measuring the degradation of methylene blue under UV light irradiation. SEM images indicated that the morphology of ZnO-Ag nanocomposites has a spherical shape with a particle diameter of around 65 nm. Moreover, increasing the flow rate will increase the particle size of the produced nanocomposites. The photocatalytic test was determined based on the rate constant of MB degradation efficiency under UV light irradiation, where the photocatalytic activity decreased when the carrier gas increased. Finally, the produced nanocomposites were also tested several times (recycling test), where photocatalytic performance showed that the degradation value of methylene blue for each recycle did not vary much with the variable before being recycled.

“…MB is a dyestuff that is difficult to degrade by microorganisms. Therefore this dye must be removed out from the waste of the textile industry before being discharged into the aquatic environment 1 . Adsorbents such as activated carbon [2][3][4][5] and activated natural zeolite 6 have been prepared and used to adsorb dyestuff from aqueous solution.…”

The natural zeolite green color (GCNZ) from Ende-Flores, Indonesia has been activated with several acid solution series, characterized by XRF spectroscopy and used for methylene blue (MB) adsorption from aqueous solution. The characteristic of XRF showed that the natural zeolite has mainly composed of mordenite with Si/Al ratio of GCNZ before and after acid activated is 7.34 % and 16.28 % respectively. Surface area study was found out using the methylene blue adsorption method whereas adsorption process was done by the batch system. It was shown that average of surface area for GCNZ and activated green color natural zeolite (AGCNZ) is 49.069 m 2 /mol and 265.946 m 2 /mol respectively. The maximum adsorption capacity of MB onto the surface of GCNZ is 42.441 mg/g whereas AGCNZ is 87.592 mg/g. Kinetic modeling studies showed the adsorption process fits with pseudo-first-order rate mechanism. Isotherm studies show that adsorption process is best to describe by Freundlich isotherm model. Also, the thermodynamic process indicates that adsorption is an exothermic process and spontaneous.

“…Most of the biomass wastes are either burnt in the open or disposed of in waste ponds. Therefore, palm oil industries contribute significantly to global warming by emitting carbon dioxide and methane gases 4 . Along with palm oil wastes problem, colored effluent from textile industries that used synthetic dyes often creates other environmental problems.…”

In this report, we prepared activated charcoal from oil palm midrib and used it as an adsorbent to decolorizeReactive Red and Direct Green as synthetic dyes in the sample solution. The response of various experiments conditions, such as contact time, solution pH, temperature, the weight of adsorbent, and concentration of dyes, on adsorption of synthetic dyes, were evaluated along with the analysis of isotherms, kinetics, and thermodynamics adsorption parameters. At equilibrium, adsorption of dyes onto activated charcoal fitted well to Freundlich model giving coefficients of correlation R 2 ≥ 0.9. At optimum conditions, capacities of adsorption for Reactive Red 120 and Direct Green 26 were 151 and 116 mg/g, respectively. The kinetics study suggested that dyes adsorption onto activated charcoal followed the model of pseudo-second-order with thermodynamic parameters of ∆G°, ∆H°, and ∆S° were -0.21 to -3.93 kJ/mol, -30.15 to -36.12 kJ/mol, and 0.003 J/mol.K, respectively. Based on the experiments, we conclude that dyes adsorption was exothermic, spontaneous and an increase in the system entropy. The results of FT-IR analysis indicated the involvement of various functional groups, including hydroxyl and amine groups. This study emphasizes the potential of oil palm waste as an alternative low-cost adsorbent for the removal of dyes.
