Assessment of polyethylene/Zn-ionic as a diesel fuel sulfur adsorbent: gamma radiation effect and response surface methodology

Wide use of 2-Amino-4-Acetaminoanisole (AMA) as a coupling component in the synthesis of many commercial dyes leads to the generation of AMA dyed wastewater. Discharge of untreated AMA dyed wastewater could bring environmental concerns. The present study featured H 2 O 2 heterogeneous Fenton system to degrade 2-Amino-4-Acetaminoanisole from wastewater using nano-Fe 3 O 4 catalyst prepared via the co-precipitation method. Based on a single factor and taking the AMA removal rate as the response value, the Box-Benhnken (BBD) response surface method was used to investigate the individual effects of Fe 3 O 4 dosage, H 2 O 2 dosage, initial pH, and reaction time. For the interaction study, the experimental data were processed with Design-Expert 10.0 software to obtain a quadratic response surface model. The results showed that the order of the in uence of the four independent variables on the response value is as follows: nano-Fe 3 O 4 dosage > H 2 O 2 dosage > reaction time > pH. The obtained mathematical model exhibited a high degree of t with the maximum AMA removal e ciency reaching to 100%. The optimal reaction conditions considered in this study are 1.70 g/L of Nano-Fe 3 O 4 dosage, 53.52 mmol/L of H 2 O 2 dosage, pH 5.14 and 388.97 mins as system reaction time. Furthermore, HPLC-MS was employed to analyze the degradation mechanism of AMA and the reaction intermediate products. Findings of this research provides fundamental theory and could guide subsequent practical AMA treatment during wastewater treatment.

Synthesis and catalytic application of polymeric-based nanocomposites are important subjects among researchers due to their high lipophilicity as well as high chemical and mechanical stability. In the present work, a novel nanocomposite material involving ionic liquid and high-density polyethylene supported tungstate (PE/IL-WO4=) is synthesized, characterized and its catalytic application is investigated. The coacervation method was used to incorporate 1-methyl-3-octylimidazolium bromide ([MOIm] [Br]) ionic liquid in high-density polyethylene, resulting in a PE/IL composite. Subsequently, tungstate was anchored on PE/IL to give PE/IL-WO4= catalyst. The PXRD, FT-IR, EDX, TGA, and SEM analyses were used to characterize the PE/IL-WO4= composite. This material demonstrated high catalytic efficiency in the synthesis of bioactive tetrahydrobenzo[a]xanthen-11-ones under green conditions. The recoverability and leching tests were performed to investigate the stability and durability of the designed PE/IL-WO4= catalyst under applied conditions.
