Cefixime removal via WO3/Co-ZIF nanocomposite using machine learning methods

Scientific Reports, Journal Year: 2024, Volume and Issue: 14(1)

Published: June 15, 2024

Abstract In this research, an upgraded and environmentally friendly process involving WO 3 /Co-ZIF nanocomposite was used for the removal of Cefixime from aqueous solutions. Intelligent decision-making employed using various models including Support Vector Regression (SVR), Genetic Algorithm (GA), Artificial Neural Network (ANN), Simulation Optimization Language Visualized Excel Results (SOLVER), Response Surface Methodology (RSM). SVR, ANN, RSM were modeling predicting results, while GA SOLVER to achieve optimal conditions degradation. The primary goal applying different best with high accuracy in Based on R analysis, quadratic factorial model selected as model, regression coefficients obtained it evaluate performance artificial intelligence models. According interactions between pH time, catalyst amount, well reaction time amount identified most significant factors results. a comparison based Mean Absolute Error (MAE), Root Square (RMSE), Coefficient Determination (R 2 Score) indices, SVR prediction higher Score (0.98), lower MAE (1.54) RMSE (3.91) compared ANN model. Both important parameter Algorithm, initial concentration had greatest impact selecting values. Using models, optimum values Cefixime, pH, determined be (6.14 mg L −1 , 3.13, 117.65 min, 0.19 g ) (5 3, 120 ), respectively. Given presented research can contribute significantly advancements intelligent optimization pollutant processes environment.

Conjugated Microporous Polymers‐Based Catalytic Membranes with Hierarchical Channels for High‐Throughput Removal of Micropollutants

Advanced Science, Journal Year: 2024, Volume and Issue: 11(29)

Published: June 3, 2024

Abstract Engineering a catalytic membrane capable of efficiently removing emerging organic microcontaminants under ultrahigh flux conditions is significance for water purification. Herein, drawing inspiration from the functional attributes lymphatic vessels involved in immunosurveillance and fluid transport with minimal energy consumption, novel hierarchical porous engineered. This membrane, based on an innovative nitrogen‐rich conjugated microporous polymer (polytripheneamine, PTPA), synthesized using electrospinning coupled situ polymerization approach. The resulting bioinspired channels comprises thin layer (≈1.7 µm) crosslinked PTPA nanoparticles covering interconnected electrospun nanofibers. unique design creates intrinsic angstrom‐confined system activating peroxymonosulfate (PMS) to generate 98.7% singlet oxygen ( 1 O 2 ), enabling durable highly efficient degradation microcontaminants. Additionally, presence mesoporous structure between macroporous within interwoven nanofibers enhances mass transfer efficiency facilitates high rates. Notably, prepared demonstrates enduring high‐efficiency performance superior permeance (>95% >2500 L m −2 h −1 bar ) sustained over 100 h. work introduces pathway high‐performance membranes removal
