Abstract

Developing composite beads composed of chitosan, alginate, and activated carbon for dye removal is essential due to their improved adsorption capabilities and environmental benefits. By utilizing natural resources efficiently for an effective dye removal process, this study developed an activated carbon/alginate/chitosan composite bead as Rhemazole Brilliant Blue R (RBBR) adsorbent. The surface shape of composites exhibits more protrusions, grooves, and asymmetric pores than activated carbon, which could improve dye adsorption capability. FTIR analysis verified that functional groups such as OH, NH, protonated amine, and carboxylate from the constituent polymers were enriched in the activated carbon/alginate/chitosan composite. These groups also function as active sites for adsorbents. It was aligned with the composite beads' Freundlich isotherm model, which shows that heterogeneous or many active sites contribute to adsorption and provide multilayer adsorption. The kinetic model of pseudo-second order fits well with the adsorption process, indicating that chemisorption is the rate-limiting step in RBBR adsorption. The optimum adsorption conditions were at pH 1, with an adsorbent dose of 0.08 g, RBBR dye concentration of 125 mg/L, and a contact time of 60 min. The composite beads also exhibit stability in acidic and basic solutions, with the effectiveness of being reused up to four times, providing a reusable adsorbent with versatility in various water treatment conditions. Hence, synthesizing activated carbon/alginate/chitosan composite beads presents a promising solution for sustainable wastewater treatment based on biodegradable and eco-friendly composite.

Abstract

In this study, rambutan (Nephelium Lappaceum L.) seeds were used to fabricate green carbon dots (gCDs) by employing a hydrothermal process. The synthesized CDs were evaluated using Fourier transform infrared (FT-IR) and X-ray photoelectron spectroscopy (XPS) for the structural properties as well as UV-Vis and fluorescence spectrophotometry for the optical properties. UV-Vis examination revealed that the produced gCDs showed emission-dependent photoluminescence excitation, with two absorption peaks at 265 nm and 330 nm. The presence of functional groups and chemical composition such as C=C, C=O, -COOH, and -OH on the surface of gCDs was confirmed by the results of FTIR and XPS spectra. Consequently, gCDs present several opportunities for exploration in a range of applications.

Abstract

Low-Density Polyethylene (LDPE) is one of the most popular and commonly used petroleum-derived thermoplastics for packaging. The large production of LDPE has an environmental impact. Reducing production can be done by recycling LDPE (r-LDPE) and adding organic fibres as a filler that is easily decomposed. Cattle farming solid waste as a fibre source was mixed with r-LDPE with coupling agent maleic anhydride (MA). Before use, the cow manure was processed through a bleaching and hemicellulose removal process, which resulted in Cow Manure Fiber (CMF). The CMF was analyzed using FTIR spectroscopy and microscopic fibre dimension analysis. The FTIR results showed peaks at wavenumbers 3538 and 1056 cm-1, representing the -OH, -C-O and -CH functional groups from the cellulose structure. The resulting composites were tested for physical properties, including elastic modulus, yield stress, and elongation. Pure LDPE material was also used for comparison. The best physical properties of the composites were obtained by composites with 95% r-LDPE, 5% CMF, and 2% MA.
