Abstract This study explores the potential of utilizing weathered basalt waste, discarded from stone quarrying, as a resource for producing efficient adsorbents to remove Fe (III) and Zn (II) aqueous real wastewater. Raw (RWB), its calcined derivatives at 750 °C 3 h (CWB-750) 950 1 with activated carbon impregnation (CWB/AC-950), were prepared characterized. Characterization using XRD, FTIR, SEM, surface area analyzer revealed that calcination improved porosity some privilege CWB/AC-950. CWB/AC-950 remarkable removal efficiency pH value 5, achieving 98.30%, closely matching RWB (98.00%), outperforming CWB-750 (96.20%). In contrast, exhibited highest capacity 6, an 55%, surpassing both CWB/AC-950, which achieved approximately 36%. For contaminants, Pseudo-2nd-order equation ( R 2 > 0.98) provided superior fit, showcasing favorable sorption process by all addressed materials. The Fe(III) data investigated materials better described Freundlich (FL) model compared Langmuir (LM) model. Similarly, Zn(II) (CWB-750 CWB/AC-950) well-explained FL These findings are supported very high determination coefficients 0.96) significantly lower average relative error (ARE) values (8.66 13.69) those obtained LM (55.99 189.25, orderly). RWB, despite (> models, neither adequately captured behavior, evidenced exceptionally ARE (52.67 161.19 FL, respectively). remediation mechanism was not exclusively governed inter-particle diffusion. Eventually, these highlight sustainable repurposing waste water applications.

From Textile and Mine Waste Into Sustainable, Low‐Cost and Valuable Nanotextile Fabric‐Based Composites Through Electrospinning Technique

Polymers for Advanced Technologies, Год журнала: 2024, Номер 35(11)

ABSTRACT The rapid expansion of textile industries has contributed significantly to non‐biodegradable waste generation, presenting a global environmental challenge. Additionally, from the mining industry, such as chrysotile serpentine, contributes this issue. Therefore, study investigates possibility recycling polyamide 6 combined with serpentine produce nanotextile fabric‐based composite (NTF‐BC). This highlights significance sustainable techniques in management specifically within industry. was intensively pulverized into nanoscale particles eliminate its hazardous fibrous nature and facilitate electrospinning process. Comprehensive characterization conducted using various analytical including XRD, XRF, FT‐IR, SEM, BET, DMA, explore properties prepared fabrics function parameters (Ctl.Sp concentration, spinning distance, applied voltage, flow rate.). SEM analysis indicated optimal fabrication conditions for smoother more homogeneous NTF‐BC at Ctl.Sp concentration 7.5%, voltage 20 kV, distance 15 cm, rate 1 mL/h. XRD FT‐IR analyses showed that increasing ratio, negatively affected sample crystallinity favored α‐form over γ‐form. In terms DMA characteristics, ratio positively impacted E ′ values, minimal influence rate. Notably, highest geometric (i.e., S BET V t ) fabricated were attained lowest 5%.
