Dye pollution from industrial effluents continues to raise environmental and health concerns, particularly because colored wastewater is difficult to treat with conventional methods. Among available treatment technologies, adsorption is widely regarded as one of the most efficient and economically feasible methods for dye removal. To interpret adsorption performance and infer possible adsorption behavior, equilibrium isotherm and kinetic models are routinely applied and are often treated as methodological requirements in adsorption studies. However, recurring misconceptions in the selection, fitting, and interpretation of these models remain evident in the dye adsorption literature. This review provides a critical reassessment of classical and extended isotherm models (Langmuir, Freundlich, Temkin, Dubininโ€“Radushkevich, Redlichโ€“Peterson, Sips, and Toth) as well as widely used kinetic models (pseudo-first-order, pseudo-second-order, intraparticle diffusion, Elovich, and Boyd). Beyond summarizing equations and assumptions, the review systematically identifies persistent interpretive patterns, including the overinterpretation of pseudo-second-order fitting as proof of chemisorption, the use of Dubininโ€“Radushkevich energy values as binary indicators of physical versus chemical adsorption, and the reliance on linearized forms and R2 as primary criteria for model selection. By distinguishing statistical agreement from mechanistic validity and by outlining evidence-based boundaries for parameter interpretation, this work aims to provide clearer methodological guidance for adsorption modeling practice and to support more reliable analysis of dye removal systems.

The various color was not significantly affected on the growth parameters. However, black and silver mulches (T2 and T3) exhibited highly significant and consistent impacts on yield performance, such as number of flower bud emergence where T2 (Black) obtained the highest number of 223.13, weight of fruit (T2 - 503.35 g and T3 - 490.79 g respectively), and overall fruit yield (t ha-1) where T3 (41.98 t ha-1) obtained comparable results in T2 (41.10 t ha-1), resulting in the highest Return on Investment (ROI). Consequently, it is determined that T3 (Silver) and T2 (Black) consistently demonstrated yield performance, making them favourable choices for local growers seeking to enhance the productivity and economic returns of red-fleshed dragon fruit cultivation in the region. Adopting black and silver mulches is based on their consistent and comparable positive results on yield performance, which is recommended for local dragon fruit growers in Claveria, Misamis Oriental Agro-ecosystem.

Ficus nota (Blanco) Merr., locally known as "Tibig" or "Tobog," is an endemic Philippine species with traditional medicinal and commercial uses. This systematic review synthesizes literature on F. nota's phytochemical constituents, biological activities, clinical translation potential, and conservation implications from 2006 to 2025. Following PRISMA guidelines, 39 studies were analyzed covering chemical synthesis (38%), conservation studies (24%), agricultural applications (18%), medicinal properties (15%), and antimicrobial activities (5%). Results revealed bioactive compounds ficusnotins, phenols, flavonoids, and tannins exhibit anti-diabetic activity comparable to standard reference drugs in some studies, along with antimicrobial properties and potential agricultural applications. The review evaluated biological activity, clinical translation challenges, including narrow therapeutic windows, standardization requirements for commercial development, and conservation strategies. Research gaps included the absence of clinical trials, inadequate mechanistic understanding, and insufficient conservation frameworks. This review provides the first synthesis integrating F. nota's pharmaceutical potential, agricultural applications, and conservation needs, establishing a framework for evidencebased development while preserving this endemic species.

๐—”๐—ฏ๐˜€๐˜๐—ฟ๐—ฎ๐—ฐ๐˜:
Environmental pollution, particularly due to heavy metals, is a growing global issue, with industries like electronics making a significant contribution. The uncontrolled and intensive processing of electronic waste (e-waste) has resulted in the widespread release of heavy metals into the environment, leading to elevated concentrations in nearby air, water, soils, sediments, and agriculture. Among these pollutants, metals such as copper and nickel, commonly discharged from printed circuit board (PCB) manufacturing, pose significant environmental and health threats due to their high toxicity. This investigation explores the simultaneous removal and recovery of copper (Cuยฒโบ) and nickel (Niยฒโบ) ions from synthetic printed circuit board (PCB) wastewater through the application of a fluidized-bed homogeneous granulation technique. The research specifically examines how key operational variablesโ€”namely, the flow rate of the carbonate precipitant, pH, and carbonate ion concentration, influence both metal removal efficiency and granule formation. The synthetic effluent used in the trials contained copper and nickel ions at initial concentrations of 6.3 mM and 3.4 mM, respectively. Experimental conditions were maintained at a pH of 6.5, with a total carbonate concentration of 17 mM. Findings indicated that a precipitant flow rate of 15 mL/min was optimal for effective copper removal and granulation, whereas nickel demonstrated superior removal performance at a higher flow rate of 25 mL/min. Elevated flow rates, however, were observed to reduce granulation efficiency and promote sludge accumulation, thereby hindering the overall performance of the system. Morphological analysis via scanning electron microscopy (SEM) revealed granules with irregular surfaces and notable porosity, likely due to the concurrent precipitation of multiple metal species. The results underscore the viability of fluidized-bed granulation as a promising, sustainable, and cost-effective approach for treating heavy metal-laden industrial wastewater. Nonetheless, further refinement of process parameters is recommended to enhance metal recovery yields and granule quality.
