Chitosan (CS) is a naturally occurring polycationic linear amino polysaccharide produced commonly through the deacetylation of chitin. This study describes synthesis modified with sodium tripolyphosphate (STPP) using an efficient coated Cross-linked method. The investigated efficacy chitosan-tripolyphosphate (CS-STPP) nanoparticles for adsorption As (III) ions from wastewater solution. effect initial Arsenic ion concentration, solution pH, and temperature on efficiency was thoroughly investigated. highest capacity CS-STPP nano adsorbents found to be 39.8 mg/g 39.6 mg/g, respectively, at pH 5.5, 30 °C. FESEM, SEM, HRTEM, XRD, FTIR, DLS, TGA results indicated that process chemically dominating. Determine anodic sweep voltammetry 797 VA Computrace (Metrohm). Langmuir parameters 40.9 1000 L/mg were maximum capacity, which monolayer homogeneous site, Freundlich isotherm applicable multilayer onto heterogeneous sites. thermodynamic showed by spontaneous, feasible, exothermic temperatures ranging °C 50 kinetic model processes persist well pseudo-second-order kinetics model. reaction suitable model, it indicates inclination chemisorption. Adsorption-desorption are determined bio adsorbent several physicochemical cycles. All indicate prepared might considered cost-effective removing wastewater.

Globally, ecosystems and human health are at risk due to declining river water quality. The current study focuses on the River Asan, Uttarakhand, which faces significant quality challenges various environmental, industrial, domestic factors. This research presents an exhaustive that intricately blends local community perceptions with scientific data, employing Geographic Information Systems map across seven critical locations along river. Participatory Rural Appraisal (PRA) systematic test methods were applied find objective of this study. highlights importance considering social, cultural, environmental factors in understanding issues. detailed, location-specific analysis, enriched by vast array insights, offers a unique lens through each site examined. Significant findings represent Nayagaon, from 2019 2023, rising temperature (1.6 °C increase) decreasing pH (7.3–6.5) observed. Reduced dissolved oxygen (9.7–6.1 mg/L) aligns concerns about quality, highlighting urgent need for interventions protect Asan its dependent communities. Integrating data provides nuanced issues, emphasizing targeted safeguard ecosystem well-being communities it, thereby offering valuable insights sustainable management.
