The composite was characterized using X-ray fluorescence (XRF), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), Brunauer–Emmett–Teller (BET) analysis, and pH at zero-point charge (pHzpc). The material exhibited high SiO₂ and CaO content, functional groups (e.g., Si–O-Si, N–H, O–H, C–O, C–N, and O–C.), a rough and heterogeneous surface morphology, a surface area of 105.96 m²/g, and a pHzpc of 11.25. Batch experiments determined optimal adsorption conditions: 200 rpm shaking speed, 120-min contact time, pH 7, particle size of 2.36–3.35 mm, and dosage of 57 g/L. The Langmuir isotherm model provided the best fit for NH₃-N and COD adsorption with adsorption capacities of 26.18 mg/g and 47.39 mg/g, respectively (<i>R</i>² = 0.9941 and 0.9814). Kinetic studies indicated pseudo-second-order kinetics, suggesting chemisorption as the rate-limiting process. These findings demonstrate the composite (PS, LS, ZEO, and AC) potential as an efficient and sustainable adsorbent for treating stabilized landfill leachate. Further studies should focus on evaluating the performance of composite adsorbents for the removal of NH₃-N, COD, or other pollutants from mining industry, domestic, or combined effluents, as well as their potential application in air pollution control.</p></div>","PeriodicalId":8374,"journal":{"name":"Applied Water Science","volume":"15 5","pages":""},"PeriodicalIF":5.7,"publicationDate":"2025-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s13201-025-02433-1.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143793172","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, waste polystyrene (W) underwent methacrylic acid grafting in the absence of zinc cobalt oxide, serving as a control reference material, denoted as m-W, to evaluate the impact of ZC incorporation on the composite’s structural and catalytic properties. The synthesized polymers were employed for poroxymonosulfate activation (PMS) in the catalytic removal of methylene blue (MB) from wastewater streams. Through systematic experimentation, we compared three different loadings of m-WZC composites (m-WZC₁₀, m-WZC₁₅, and m-WZC₃₀) by optimizing key degradation parameters, including PMS dose, pH, temperature, initial MB concentration, and the effect of ions. Among them, m-WZC₁₅ exhibited the optimal performance, achieving 99.89% MB removal within just 10 min at an initial MB concentration of 20 mg/L.

Utilizing monthly water quality data, the model generates normally distributed datasets that are processed through the TOPSIS model, incorporating RF-derived weights and a membership function, for a comprehensive evaluation. Validation of the model demonstrated a predictive accuracy rate exceeding 83.87%, outperforming other assessment methods such as the analytic hierarchy process, criteria importance through intercriteria correlation, the evidential weighting method, and the COV method. The MCS significantly reduced uncertainties linked to multiple indicators, thereby enhancing the reliability of the assessments.

A global sensitivity analysis identified chemical oxygen demand (COD), biochemical oxygen demand (BOD₅), total phosphorus (TP), and potassium permanganate index (COD_Mn) as critical determinants of water quality.

However, another method that is as effective as this method is pervaporation (PV). The most important component that affects performance in both methods is the membranes. In this study, zirconium-based metal organic framework (MOF) material was synthesized and added to the polylactic acid (PLA) membrane and boron was removed by pervaporation and membrane distillation methods.

The effect of MOF additive on the morphology, mechanical strength, and separation properties of the membrane was investigated. Additionally, the effects of boron concentration and temperature on the separation performance in both methods were examined. As a result, the mechanical strength of membranes with MOF added increased significantly from 2.41 to 8.20 MPa. 99.9% boron removal was achieved in both methods.

Therefore, the present study was designed to evaluate the microbial quality of swimming pool and pond waters in Lahore City, Punjab, Pakistan. For this purpose, 10 swimming pools and 10 ponds in the study area were selected.

This study tried to delineate the UGAW and its sub-watersheds, compute basic morphometric parameters, and link each value with its drainage characteristics. Ranking and prioritization of the sub-watersheds were also done to suggest future interventions. GIS and remote sensing techniques were utilized to delineate the sub-watersheds and compute 32 selected basic morphometric parameters. A 12.5-m resolution ALOS PALSAR DEM was the input data used in GIS software to analyze and characterize the hydro-geo-morphometric features. The findings indicated that the watershed exhibits a dendritic pattern with six stream orders. A 1314.4 km total flow length for all orders is distributed within a 1657.5 km² catchment area. The infiltration number is high, causing greater surface runoff, while its low circularity ratio (0.27), elongation ratio (0.52), and bifurcation ratio (2.1) connote the basin’s nearly compact shape. Besides, it has high basin relief (1650 m), slope, and ruggedness number, implying high erosional potential in the area. Generally, the watershed experiences high runoff and minimal infiltration, making it highly prone to soil erosion and land degradation. UGAW was divided into six sub-watersheds (SW1–SW6), each characterized by distinct hydro-geo-morphometric features. The prioritization of these sub-watersheds was based on 20 purposely selected parameters. Consequently, the sub-watersheds were ranked from highest to lowest priority as follows: SW6, SW5, SW4, SW3, SW1, and SW2.
