A pretreatment using air stripping (aerobic pretreatment; AP) was first applied and compared to anaerobic pretreatment (ANP). The COD and BOD5 were highly removed by AP, reaching 86% and 88% compared to ANP, which only achieved 48% and 55%, respectively. Following the AP, the sono-photo-Fenton (SPF) process was applied as post-treatment. The optimal conditions pH = 3, [H2O2] = 1834 mg/L, and [Fe2+] = 1281 mg/L improved the COD, color and BOD5 removal of 96%, 98%, and 98%, respectively. Turbidity, N-NO3-, and N-NO2- were completely removed (100%) by the combined processes (AP+SPF), while Cr, Cl-, and N-NH4+ were reduced to 99%, 97%, and 99%, respectively. Finally, phytotoxicity tests were performed to confirm the efficiency of the sequential processes. The highest germination percentage, germination rate index, and seedling vigor index for the grains wheat and Medicago sativa were observed using the TWW treated by the AP+SPF, followed by those treated by AP alone. In contrast, no germination indicators were noticed in raw TWW. These findings highlight the significant purification effectiveness of the sequential processes of AP and SPF post-treatment, which suggests the potential use of this combination for the efficient treatment of real liquid effluents.","PeriodicalId":14235,"journal":{"name":"International Journal of Phytoremediation","volume":" ","pages":"1-14"},"PeriodicalIF":3.4,"publicationDate":"2025-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144010136","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study researched the impact of rape (Brassica campestris) cultivation and influence of straw management on Cd accumulation in rice (Oryza sativa L.) under rape-rice rotation system. Field experiments were set in moderately Cd-contaminated farmlands, with treatments including rape-rice rotation with straw removal (NR), rape-rice rotation with straw return (RR), and single cropping rice (SR). In contrast with SR, the NR effectively reduced 6.67-19.59% soil available Cd and the 37.18-39.10% rice grains Cd accumulation during 3 years. Compared with the RR, SR significantly decreased 17.17-27.78% soil available Cd concentrations and 33.30-53.84% rice grain Cd accumulation. Soil physical and chemical properties were influenced by rape cultivation and straw return, further affecting Cd mobility. This study underscores that rape-rice rotation with straw removal can be an effective tactic for reducing the Cd contamination in rice grains and improve soil environment.

The physicochemical properties of MSP were characterized via XRD, FTIR, FESEM-EDX, and pHpzc analysis. The biosorption process was optimized using the Box-Behnken design (RSM-BBD), to evaluate the influence of MSP dose (0.02-0.1 g/100 mL), contact time (20-300 min), and solution pH (4-10). The desirability function further refined and validated the BBD results, demonstrating that maximum MB removal (98.7%) was achieved at an MSP dose of 0.09 g/100 mL, contact time of 276.1 min, and solution pH of 8.7. Kinetic modeling indicated that MB biosorption onto MSP conformed to the pseudo-second order (PSO) model. The intraparticle diffusion (IPD) model supports a multi-step adsorption process, consisting of surface adsorption, gradual diffusion, and equilibrium stages. The adsorption equilibrium data were well described by the Langmuir and Freundlich isotherm models, confirming a combination of monolayer and multilayer adsorption profiles. The maximum adsorption capacity (qmax) of MSP was estimated to be 128.3 mg/g. The biosorption mechanism was attributed to hydrogen bonding, π-π interactions, electrostatic forces, and pore filling, as evidenced by spectroscopy and bioadsorbent morphology results. The reusability study demonstrated that MSP retained significant adsorption capacity over multiple cycles, highlighting its moderate recyclability.

The impacts of exogenous Si application on root morphology, enzymatic activities, proline and glycine betaine (GB) accumulation, reactive oxygen species (ROS), and other physiological parameters of cabbage plants grown under Ni stress were observed. Exogenous Si mitigated the irreversible damage caused by Ni by improving root morphology, enhancing plant enzymatic activities, regulating osmoprotectants (proline and glycine betaine), modulating ROC (<math><mrow><msubsup><mrow><mi>O</mi></mrow><mrow><mn>2</mn></mrow><mrow><mo>-</mo></mrow></msubsup></mrow></math> and H2O2), and supporting overall plant physiology. Furthermore, Si reduced Ni content by 67% and 72% in roots and leaves, respectively, and improved the nutrients (Si, N, P, and K) upregulation under Ni stress while reducing oxidative stress. The overall findings suggest that foliar application of 2 mM Si can enhance root morphology, regulate nutrient uptake, and play a crucial role in reducing Ni accumulation. This effect is primarily attributed to its contribution to strengthening plant defense mechanisms against oxidative damage and regulating osmoregulation, thereby alleviating Ni-induced stress and promoting plant growth.","PeriodicalId":14235,"journal":{"name":"International Journal of Phytoremediation","volume":" ","pages":"1-11"},"PeriodicalIF":3.4,"publicationDate":"2025-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144008083","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
