In the present study, Agaricus bisporus mushroom (ABM) and its spent mushroom compost (SMC) samples are used as biosorbents to find and compare their efficiency for the removal of Cu(II) and Ni(II) ions from aqueous solutions. The optimal conditions for maximum biosorption were obtained at pH 5, 0.5 g biosorbent dosage per 10 mL, 6 h of contact time, and initial concentration of 17 and 30 µg/mL for Cu (II) and Ni(II). Pseudo second order kinetic model, with (R2 > 0.999) for both the metals and Freundlich isotherm model with (R2 > 0.959) for Cu(II) and (R2 > 0.985) for Ni(II) best described the biosorption data. Thermodynamic analysis revealed the spontaneous and endothermic nature of the biosorption process. The SEM, EDX, and FTIR analysis were conducted to determine the metal uptake and presence of functional groups responsible for biosorption of metals. FESEM analyses has confirmed the surface morphology; the presence of Cu(II) and Ni(II) peaks after adsorption were confirmed by EDX; and the FTIR study confirmed the presence of hydroxyl, carboxyl, amine, phosphate, and amide functional groups in the biomass. The results demonstrated that SMC exhibited greater biosorption efficiency [93.88% for Cu(II) and 88.5% for Ni(II)] than ABM [91.43% for Cu(II) and 86.63% for Ni(II)], in order Cu(II) > Ni(II), making both viable options for the removal of heavy metals from aqueous medium. Furthermore, both the biosorbents have shown remarkable regeneration and recyclability up to eight adsorption-desorption cycles with appreciable adsorption for both the metals.","PeriodicalId":14235,"journal":{"name":"International Journal of Phytoremediation","volume":" ","pages":"1-18"},"PeriodicalIF":3.4,"publicationDate":"2025-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144173846","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 process effectively treated 500 mL of synthetic wastewater containing 100 ppm zinc ion and the process could be enhanced to achieve the removal efficiency of 90% by adjusting the solution pH to slightly acidic (pH 5) and increasing the mass of duckweed to its saturation point (20 g). Excessive zinc intake by duckweed led to chlorophyll reduction, negatively impacting the duckweed growth rate. Scanning electron microscopy (SEM) analysis revealed that the duckweed fronds' surface became uneven after the treatment, with the irregular small particles attached due to cellular damage.

Key soil parameters, including pH, moisture, and organic carbon, were monitored to study their effects on geotextile biodegradation and plant growth. Our findings indicate that jute geotextiles offer a sustainable alternative to synthetic materials, degrading within 1-2 years while promoting vegetation, making them ideal for short to medium-term projects.

Soil samples containing 5 mg kg-1 of EDTA were spiked with 200, 500, and 1000 mg kg-1 of Pb, while the control group (unspiked) without EDTA addition was used. The results indicated that adding EDTA in winter (winter + EDTA) significantly increased (p < 0.05) plant growth by 18.83%. Observing the seasonal variation, the removal efficiency of Pb was achieved in this order: summer + EDTA > winter + EDTA > summer + No EDTA > winter + No EDTA. The results also showed that the removal rate had improved up to 52.53% as the concentration of Pb rose from 67 to 500 mg kg-1 but showed a decline after reaching 1000 mg kg-1, indicating a maximum Pb stress level. Additionally, the EDTA chelation during winter demonstrated a significant effect on the ability of Brown mustard to accumulate higher levels of Pb in both roots and leaves, with 500 mg kg-1 as the optimal level taken by the plant throughout the experiment.

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}
