Prediction of degradability of micropollutants by sonolysis in water with QSPR - a case study on phenol derivates

Ultrasonics Sonochemistry, Journal Year: 2021, Volume and Issue: 82, P. 105867 - 105867

Published: Dec. 8, 2021

The increasing quantity and variety of organic contaminants discharged into surface groundwater increase the necessity additional suitable water treatment methods, which can be incorporated existing wastewater plants. huge micropollutants local variability composition load or matrix effects paired with multiple possible degradation processes lead to requirement a recommendation tool for best method under given conditions. Due diversity physicochemical properties micropollutants, such predictions are challenging. In this study, quantitative correlation between structural certain their degradability using high-frequency sonolysis has been investigated. Therefore, Quantitative Structure-Property Relationship (QSPR) applied on set phenol derivates. To obtain kinetic data, all experiments have conducted in standardized, constant conditions 32 investigated QSPR modelling was then executed software PaDEL descriptor calculation QSARINS overall process including genetic algorithm (GA) linear regression (MLR). final model consisting 5 molecular descriptors selected multi-criteria decision-making based extensive statistical parameters. predictive power robustness evaluated by means internal cross validation external an independent set. showed very good values abilities, as well stability (R2adj = 0.9455, CCCtr 0.9777, Q2loo 0.9285, CCCext 0.9797 Q2ext-F1 0.9711). applicability domain defined Williams plot Insubria plot. five OECD principles application QSPR/QSAR industry regulation were fulfilled whole our knowledge, collection underlying experimental data entire process. included polarity occurrence hydrogen bonds major influences reaction rate constants accordance previous studies. Nevertheless, potential biases selection these due small size dataset highlighted.

Microfiltration Membranes for the Removal of Bisphenol A from Aqueous Solution: Adsorption Behavior and Mechanism

Water, Journal Year: 2022, Volume and Issue: 14(15), P. 2306 - 2306

Published: July 25, 2022

This study mainly investigated the adsorption behavior and mechanism of microfiltration membranes (MFMs) with different physiochemical properties (polyamide (PA), polyvinylidene fluoride (PVDF), nitrocellulose (NC), polytetrafluoroethylene (PTFE)) for bisphenol A (BPA). According to isotherm kinetic, maximum capacity these MFMs was PA (161.29 mg/g) > PVDF (80.00 NC (18.02 PTFE (1.56 mg/g), rate (K1 = 2.373 h−1) 1.739 1.086 h−1). The site energy distribution analysis showed that had greatest sites, followed by MFMs. suggested hydrophilic microdomain hydrophobic a micro-separation PVDF, which resulted in higher providing hydrogen bonding sites interaction, play synergetic role improving BPA adsorption. Due force being greater than force, more on surface capacity, but interaction contributed rate. Therefore, can influence or its analogues. These consequences provide novel insight better understanding
