Eriochrome Black T (EBT) and chromium (Cr) are considered to be potential pollutants due their toxicity severe impact on the environment. In current study, hydrotalcite-derived Mg-Ca-Al-LDO mixed metal oxide composite was prepared using a conventional co-precipitation method explored in terms of removal Cr EBT dye from aqueous solution batch mode adsorption process. The Mg-Ca-Al-LDH, spent adsorbents were characterized propose mechanism. Different parameters examined, such as adsorbent dosage, initial concentration, pH, reaction temperature contact time. kinetic results matched strongly with pseudo-second-order model for both (R2 = 0.991) 0.999). Langmuir isotherm exhibited maximum capacity 65.5 mg/g 150.3 EBT, respectively. structure morphology obtained after reveal that mechanism is associated electrostatic interactions surface complexation functional groups. Moreover, more than 84% can achieved five adsorption/desorption cycles. Finally, potentially used cost-effective wastewater treatment processes.

Abstract Fe-modified biochar (FB) and co-using Chinese milk vetch rice straw (MR) are two effective ways for mitigating the cadmium (Cd) contamination in paddy fields southern China. Nevertheless, effects of FB combined with MR on Cd passivation mechanism remain unclear. In current study, strengthening induced by were found mechanisms extracted dissolved organic matter (DOM) from co-decomposition alleviation investigated through pot experiment adsorption experiment. Pot demonstrated that co-incorporating decreased available 23.1% increased iron plaque concentration 11.8%, resulting a 34.7% reduction concentrations brown compared addition FB. Furthermore, improved nutrients soil. The molecular characteristics DOM derived decomposition (DOM-MR) analyzed fluorescence excitation emission matrix spectroscopy-parallel factor analysis (EEM-PARAFAC) Fourier transform-ion cyclotron resonance mass spectrometry (FT-ICR MS). Results showed lignin/carboxylic-rich alicyclic molecules protein/amino sugar main compounds, potentially involved binding. Adsorption experiments revealed DOM-MR functional groups, specific surface area, negative charges FB, inducing both physisorption chemisorption Cd(II). maximum capacity after adding was 634 mg g −1 , 1.30 times without DOM-MR. This study suggested MR, could serve as an innovative practice simultaneous remediation soil fertilization Cd-polluted fields. It also provided valuable insights basis optimize performances enhance its potential immobilization. Graphical
