摘要

本研究旨在从城市固体废物(牛骨)中开发一种绿色吸附剂(mgal - ldh -生物炭)来修复水中的重金属。利用x射线衍射(XRD)对mgal - ldh -生物炭进行了表征，并在不同pH、剂量、接触时间(Ct)和溶液温度(St)下对其进行了除铅实验。结果表明，当初始pH为5.0、初始Ct为80 min、初始St为45℃、初始剂量为0.2 g·L-1时，mgal - ldh -生物炭对铅的去除率为99%。

MgAl-LDH-biochar composites as a green sorbent for lead removal from water

The present study aims at the development of a green sorbent (MgAl-LDH-biochar) from the municipal solid wastes (cow bones) to remediate water from heavy metals. MgAl-LDH-biochar was characterized using X-ray diffraction (XRD), and it was used to remove lead at different pH, doses, contact time (Ct), and solution temperatures (St). The obtained results proved MgAl-LDH-biochar removes 99% of lead when the initial pH, Ct, St, and dose were 5.0, 80 min, 45°C, and 0.2 g·L–1, respectively.

期刊介绍： Scientific Review Engineering and Environmental Sciences [Przegląd Naukowy Inżynieria i Kształtowanie Środowiska] covers broad area of knowledge and practice on fields such as: sustainable development, landscaping of non-urbanized lands, environmental engineering, construction projects engineering land management, protection and land reclamation, environmental impact of investments, ecology, hydrology and water management, ground-water monitoring and restoration, geotechnical engineering, meteorology and connecting subjects. Authors are welcome to submit theoretical and practice-oriented papers containing detailed case studies within above mentioned disciplines. However, theoretical papers should contain part with practical application of the theory presented. Papers (in Polish or English languages) are accepted for publication after obtaining positive opinions of two reviewers. Papers published elsewhere are not accepted.
