Abstract

Abstract The research conducted here will hopefully lead to the creation of a practical, inexpensive method for purging aqueous solutions of contaminating phenolic chemicals. A biosorbent system comprised of eggshells and iron was studied for its potential to effectively detoxify phenol. Both the eggshell and the iron systems were used in the preparation of the adsorbents in order to achieve the desired result of having the properties of both systems. Scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), and X-ray diffraction (XRD) were used for characterisation. Batch tests were conducted to evaluate the adsorption capacity of eggshells and iron under the influence of different operating parameters (shaking speed, pH, initial phenol content, and contact time). In the design-expert modelling, the optimisation conditions were found to be a pollutant concentration = 30.0 mg . L – 1 , pH of 3.00, adsorbent dose = 0.11 mg . L – 1 , shaking speed = 150 rpm, and time = 120 min for an phenol reduction rate of 94.4 % which it was extremely near to the experimentally value (96.6 %). The CCD modelling that was performed in the RSM verified the findings that were predicted. On the basis of laboratory results, the prediction proved accurate.
铁蛋壳纳米复合材料的可持续生产及其对苯酚去除的催化潜力研究
在这里进行的研究将有望导致创建一个实用的,廉价的方法来净化污染的酚类化学物质的水溶液。研究了一种由蛋壳和铁组成的生物吸附系统对苯酚的有效解毒能力。在制备吸附剂时,同时使用了蛋壳体系和铁体系,以达到具有两种体系性能的预期结果。采用扫描电镜(SEM)、傅里叶变换红外光谱(FTIR)和x射线衍射(XRD)进行表征。通过批量试验,考察了不同操作参数(震动速度、pH、初始苯酚含量、接触时间)对蛋壳和铁的吸附能力的影响。在设计专家模型中,优化条件是污染物浓度= 30.0 mg。L - 1, pH = 3.00,吸附剂剂量= 0.11 mg。在L - 1条件下,振荡速度为150 rpm,时间为120 min,苯酚的还原率为94.4%,与实验值96.6%非常接近。在RSM中进行的CCD建模验证了预测的结果。在实验室结果的基础上,预测被证明是准确的。

期刊介绍: The quarterly Ecological Chemistry and Engineering S is a multidisciplinary journal devoted to the publishing of original scientific papers, review articles, professional papers, case reports and varia (professional information, book reviews, etc.). It is pertinent to describe methods determining quality of air, water, soils and food. Many papers published are on monitoring and biomonitoring of an environment and on transfer of pollutants (eg heavy metals or radionuclides) from soil to plants. Some Authors consider impact of environment pollution on food and human health. Some papers describe models of pollutant spreading in air or within soil. Others are devoted to various technologies to prevent or minimize industrial pollution, as well as to remediation techniques. Papers on renewable energy sources are also very welcome.
