概括

此摘要是机器生成的。

香皮和生物炭有效地从废水中去除内分泌干扰物双-A (BPA). 这项研究突出了它们作为环境修复的可持续吸附剂的潜力.

科学领域

环境化学
材料科学
处理水

背景情况

持续释放的内分泌干扰物如双甲 (BPA) 对人类健康和水生生态系统构成重大风险.
传统的去除BPA的方法往往是昂贵和低效的,需要可持续的替代方法.

研究的目的

调查生香皮和经过生物炭处理的香皮作为从水溶液中去除BPA的吸附剂的有效性.
优化吸附条件并阐明吸附机制和热力学特性.

主要方法

使用原料和经过生物炭处理的香皮进行了批量吸附实验.
包括pH值,初始BPA度,吸附剂剂量和接触时间在内的吸附参数得到了优化.
应用了动力 (伪第一阶,伪第二阶) 和等温 (Langmuir, Freundlich) 模型来分析吸附数据.

主要成果

在pH值8. 0,240 mg/ L初始BPA度,0. 4g剂量和200分钟 (原料) 和150分钟 (处理) 的接触时间下,可达到最佳吸附.
伪二阶模型最好地描述了经过处理的样品 (化学吸收),而伪一阶模型适合原始样品 (物理吸收).
最大吸附能力 (Qmax) 为91. 3 mg/ g (原料) 和135. 2 mg/ g (经过处理). 热力学研究表明自发的内热吸附过程.

结论

香皮,特别是在生物炭的形式,显示出作为一种低成本,可持续的BPA去除吸附剂的巨大潜力.
这些发现支持利用农业废物进行有效的废水处理和环境整治.

Extraction: Effects of pH

Extraction: Effects of pH

Consider a neutral form of an amine, B, with a partition coefficient, K, in a liquid mixture containing organic and aqueous phases. The pH of the aqueous phase affects the charge on acidic and basic solutes, and the charged form is usually more soluble in the aqueous phase. Suppose the conjugate acid form of the amine is soluble only in the aqueous phase while the base form is soluble in both phases. Then the distribution coefficient, D, can be given as the ratio of amine concentration in the...
