This study proposes a hybrid intelligence approach based on an extreme gradient boosting regression and genetic algorithm, namely, the XGBR-GA model, incorporating Sentinel-2, Sentinel-1, ALOS-2 PALSAR-2 data to estimate mangrove above-ground biomass (AGB), including small shrub patches in Red River Delta biosphere reserve across northern coast of Vietnam. We used novel decision tree (XGBR) technique together with algorithm (GA) optimization for feature selection construct verify AGB model...
In the present study, alumina nanoparticles (nano-alumina) which were successfully fabricated by solvothermal method, characterized X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), Transmission Electron Microscopy (TEM), and Brunauer⁻Emmett⁻Teller (BET) methods. The removal of cationic dye, Rhodamine B (RhB), through adsorption method using synthesized nano-alumina with surface modification anionic surfactant was also investigated. An surfactant, sodium dodecyl...
Quantifying total carbon (TC) stocks in soil across various mangrove ecosystems is key to understanding the global cycle reduce greenhouse gas emissions. Estimating TC at a large scale remains challenging due difficulty and high cost of measurements when number samples high. In present study, we investigated capability Sentinel-2 multispectral data together with state-of-the-art machine learning (ML) technique, which combination CatBoost regression (CBR) genetic algorithm (GA) for feature...
The present study aims to investigate adsorptive removal of molecular ciprofloxacin using protein-modified nanosilica (ProMNS). Protein was successfully extracted from Moringa seeds while synthesized rice husk. Fourier-transform infrared (FTIR), ultraviolet visible (UV-Vis) and high-performance liquid chromatography (HPLC) were used evaluate the characterization protein. Adsorption protein onto at different pH ionic strength thoroughly studied modify surface. efficiency antibiotic (CFX)...
This work aims to synthesize a core–shell material of CeO2@SiO2 based on rice husk as novel hybridized adsorbent for antibiotic removal. The phase structures and CeO2 nanoparticles that were fabricated by simple procedure examined X-ray diffraction (XRD), energy-dispersive spectroscopy (EDS), Fourier transform infrared (FT-IR) spectroscopy, while their interfacial characterizations performed scanning electron microscopy (SEM), high-resolution transmission (HRTEM), the Brunauer–Emmett–Teller...
Adsorption of the polyelectrolyte polydiallyldimethylammonium chloride (PDADMAC) onto nanosilica (SiO₂) fabricated from rice husk was studied in this work. Nanosilica characterized by X-ray diffraction, Fourier-transform infrared spectroscopy (FTIR), and scanning electron microscopy (SEM). PDADMAC SiO₂ increased with increasing pH because negative charge is higher at high pH. isotherms silica different KCl concentrations were fitted well a two-step adsorption model. mechanisms are discussed...
Environmental contextAmmonium ion, an inorganic pollutant in agricultural land, can induce eutrophication, impacting on water quality. We investigate the adsorption of ammonium ion surfactant-modified alumina and demonstrate highly efficient removal ions by from two samples. Adsorption mechanisms are also proposed based isotherms, surface modification change charge. AbstractThe adsorptive (NH4+) aqueous solution using (SMA) was investigated. The optimum NH4+ conditions SMA were...
The present study aims to investigate the adsorption of synthesized poly(2-acrylamide-2-methylpropane sulfonic acid) (PAMPs) onto alumina nanoparticles and their application in removal ciprofloxacin (CFX) antibiotic from a water environment. PAMPs were successfully characterized by nuclear magnetic resonance gel-permeation chromatography methods. number- weight-average molecular weights 6.76 × 105 7.28 106 g/mol, respectively. charge reversal nanoalumina after modification positive −37.5 mV...
