Innovative Chemically Modified Biosorbent for Removal of Procion Red

Abstract

The potential biosorbent of stinky bean peel (Parkia speciosa) (SBP) was investigated for azo dye Procion Red Mx-5B removal due to their accessibility, economically feasible, easy pretreatment, and non-toxic. This study aims to determine the effect of chemically modified of the SBP, that a massive agricultural waste in Sarawak, to enhance its ability during adsorption of dye. The biosorbent used was dried, ground, and sieved through 600 µm sieve to obtain a similar average size. Impregnation with some chemicals was performed by using ZnCl2, K2CO3, H2SO4 and NaOH for 24 h. The Freundlich, Langmuir, and Temkin techniques were examined to calculate the isotherm data. The result showed that the sorption capacity of the SBP was improved by ZnCl2 modification. The equilibrium data were fitted with the Freundlich model, while the kinetic study was fitted with the pseudo-second-order kinetic model. Further, it was concluded that dyes uptake by biosorbent was based mainly on the role of carboxyl and a hydroxyl group.

Reactive dyes adsorption via Citrus hystrix peel powder and Zea mays cob powder: characterization, isotherm and kinetic studies

“…The previous study showed that the removal of Procion Orange dye by orange peel has the highest percentage removal at pH 3 and remain the same over the range of pH 5 to pH 9 and lowest percentage removal at pH 11. Besides that, the overall percentage removal of rhodamine-B dye also shows the same trend [11,[18][19][20]. Another study on CC shows that the adsorption capacity of Methylene Blue dye by raw corn have the lowest adsorption capacity at pH 3 and adsorption capacity increased while pH increased.…”

“…Meanwhile, there are other adsorbents widely used to replace the activated carbon. Due to the toxic effect of the adsorbent that might cause the secondary pollution, it is highly recommended to find suitable adsorbent that produces less environmental impacts [11]. Therefore, many agricultural wastes have been tested to replace the adsorbent to remove the dye from the waste water effluents.…”

Adsorption of azo and anthraquinone dye by using watermelon peel powder and corn peel powder: equilibrium and kinetic studies

“…The adsorption isotherm study of the samples was conducted by manipulating the concentration of dyes in experiments. Other parameters were controlled as optimized studied and were run for 24 h. To describe the best adsorption isotherms of dyes onto the adsorbents, the following isotherm models were used [15]:…”

“…The advantages of activated carbon are large porous surface area and minimum acid or base reactivity. However, the drawback is the large portion of activated carbon needed to treat the wastewater that will increase the expenditure of the industries [13,15]. In order to achieve an acceptable level of clean water for the environment, human activities and industrial processes, adsorption using agricultural wastes is the most suitable treatment method.…”

Advanced Materials as Adsorbents in Microextractions for the Determination of Contaminants: A Mini Review

“…The presence of environmental pollutants such as herbicides, pharmaceutical waste, heavy metals (Kusumaningsih et al, 2012), and dyes (Mamat et al, 2018;Anuar et al, 2019) at trace levels has been the cause of much concern among the public and authorities. This has provided motivation for researchers to explore new materials that can be used for their removal.…”
