不同藥物的大量生產(chǎn)和使用,特別是環(huán)丙沙星,因其致命性,對(duì)環(huán)境構(gòu)成了嚴(yán)重威脅。由于這些藥物代謝不全,使其存在于水生環(huán)境中。因此,它引起了科學(xué)界的關(guān)注。用于處理水的各種材料,如石墨烯、生物炭、碳納米管、粘土礦物和蒙莫里龍石等。生物炭從廢物生物量中獲得,在改變環(huán)境補(bǔ)救方面起著至關(guān)重要的作用,如提高土壤肥力、減緩氣候變化和水處理等為了利用生物炭的多功能性,本文研究了在450℃溫度下通過(guò)熱解產(chǎn)生的不同生物炭基材料的應(yīng)用,通過(guò)應(yīng)用吸附、聲催化降解和膜過(guò)濾等不同技術(shù)從水中去除丙烯酸.吸附技術(shù)中,使用兩種基于生物炭的吸附劑來(lái)去除丙葉沙辛,通過(guò)在不同的條件下（如不同pH,不同溫度,不同的時(shí)間間隔和不同的電解質(zhì)）進(jìn)行不同的吸附實(shí)驗(yàn)來(lái)測(cè)量其吸附能力。因此,評(píng)估了不同的動(dòng)力學(xué)和吸附等溫線模型及機(jī)理。為了對(duì)環(huán)丙沙星進(jìn)行聲催化降解,將超聲輻射應(yīng)用于基于生物炭的新型聲催化劑,該超聲也用于吸附目的。為了確認(rèn)成功降解,與中間產(chǎn)品一起檢測(cè)出活性氧種（ROS）,該物質(zhì)負(fù)責(zé)降解有機(jī)物。膜過(guò)濾與其他凈水技術(shù)相比具有多種優(yōu)點(diǎn)。主要原因是多功能生物炭也建在聚合物網(wǎng)絡(luò)的膜中。制備的膜經(jīng)過(guò)不同的表征分析,經(jīng)鑒定效果良好,以最少的結(jié)垢去...
