“…In addition to these sources, activated carbons can be produced from biomass precursors, and activated carbons generated from these precursors have gained increased research attention due to their cost effectiveness, ease of fabrication, eco-friendly nature, and sustainability. Biomass precursors used to drive activated carbons include rice husks, sugarcane bagasse, corn husks, groundnut shell, jute stick, olive stones, palm shells, kenaf core fiber, peach stones, banana stems, date stones, coconut shells, bamboo, corn grain, and straw [5][6][7][8][9][10][11].…”

Tea is the third most consumed beverage in Saudi Arabia (a country in the Middle East) after water and Arabian coffee. Hence, a large amount of consumed tea leaves is discarded as solid waste. Waste tea leaves (WTLs) have no commercial value and could be considered as an environmentally sustainable costless material. This work aimed to manufacture an adsorbent material from the discarded WTLs and charge-transfer (CT) interaction and use this adsorbent material effectively for the removal of different kinds of pollutants from water. The adsorbent material was manufactured in three steps. First, a CrFeO3 metal composite was synthesized from the CT interaction between FeCl3 and CrCl3 with urea. Second, activated carbons were prepared from consumed WTLs using facile and clean treatments of pre-carbonization, and a simple potassium hydroxide (KOH) activation treatment. Finally, the adsorbent material was fabricated by grounding CrFeO3 composite with the activated carbons in a 1:10 molar ratio (metal composite to activated carbons). The prepared materials were characterized spectroscopically and morphologically using FT-IR, XRD, SEM/EDX, and TEM analysis. The synthesized absorbent material was used to adsorb two organic dyes (Azocarmine G2; M1, and Methyl violet 2B; M2), and two commercial pesticides (Tiller 480SL; M3, and Acochem 25% WP; M4) from aqueous solution, and it showed promising adsorption efficacy. The minimum adsorbent material’s dosage to obtain a maximum removal efficiency (R%) for M1, M2, M3, and M4 removal from 100 mL solution (100 mg/L) was 0.11, 0.14, 0.13, and 0.12 g, respectively. The max R% for M1 (96.8%) was achieved in the first 45 min, the max R% for M2, 95.5%, was achieved during the first 55 min, and the max R% for M3 (96.4%) was achieved in the first 35 min, while the max R% for M4, 98.6%, was achieved during the first 35 min.

“…Therefore, this problem has led to searching for low-cost yet effective alternative materials as adsorbent for removal of dye from wastewater which has become the area of interest among researchers. Researchers found that various agricultural waste can be used as low-cost adsorbent for dye wastewater treatment such as pinecone [4], Moringa Oleifera seed [5], sugarcane bagasse [6] and fox nutshell [7]. Misran et al, (2018) [8] found that using natural banana stem as adsorbent gives the high percentage for removal of Methylene Blue from wastewater as compared to activated carbon and zeolite, activated carbon and limestone 60 -89 %.…”

Wastewater effluent from the batik industry which contain dyes such as Methylene Blue (MB) will cause pollution to the adjacent water bodies if not treated effectively. A batch adsorption experiment using banana stem was conducted for various dosage (0.2 g – 1.4 g) and various contact time (15 to 120 minutes). Adsorption isotherm was employed to understand the nature of the sorption process. Feasibility of the sorption process of MB were evaluated by developing kinetics adsorption modelling, while error function suggested the best-fitted sorption model on sorption data. From isotherm analysis, the adsorption process fits the Freundlich better than other models due to r2 value, 0.917 even though Langmuir Type IV is relatively higher. In Langmuir Type IV model, the negative sign of b value signifies the surface of banana stem has heterogeneous coverage instead of homogeneous coverage. For the adsorption kinetic models, it reveals that Pseudo-Second-Order model fitted well with r2 value of 0.996. The adsorption of MB is dominated by multi-layer adsorption on the heterogeneous surface of banana stem adsorbent which influenced by chemisorption process. Therefore, banana stem has the potential as an alternative, eco-friendly adsorbent media for effective removal of dyes in textile effluents.

“…The dyes comprise of toxic and complex components, which can influence unfavorable color changes of the water due to their slow degradation rate. Furthermore, the unpleasant effect not only from aesthetic point of view, yet in addition from decreasing in sunlight penetration that reducing the activity of photosynthesis [1,2]. Dyes are widely used in industries like textile, food, cosmetics, plastics, printings and paper to color their products.…”

“…Dyes are widely used in industries like textile, food, cosmetics, plastics, printings and paper to color their products. Annually, there are about 100, 000 types of synthetic dyes with more than 70,000 tons of production from the associated industries in which 15-20% of it lost and carried away as wastewater [2,3]. Methyl orange (C14H14N3NaO3S) is one of the anionic dyes that extensively used in the associated industries and concerning to its amount and harmful effect, it is important to treat the dye components before discharging into the water body [2][3][4] .…”

In this study, carbon quantum dots (CQDs) was prepared via a facile hydrothermal method. The objective for this study is to assess the performance of CQDs in photocatalytic degradation activity of methyl orange (MO) under artificial visible light source. For that reason, the prepared photocatalyst undergo further characterization by scanning electron microscope (SEM), energy dispersive X-ray spectroscope (EDX) and UV- Vis spectrophotometer (UV-VIS) to verify the morphology structure of the photocatalyst, elemental composition as well as the absorbance intensity, respectively. The results indicates that the prepared photocatalyst possess irregular porous shape with nanometre (nm) dimensions that can escalate the surface area for photocatalytic degradation activity. The elements of the photocatalyst mainly consist of carbon and oxygen as the major constituents in which necessary for photocatalytic activity with intense peak of absorbance intensity. The prepared CQDs also shows an excellent photocatalytic performance over the MO with degradation rate of 68.9% within 120 minutes.
