Selective recovery of chromium from ferronickel slag via alkaline roasting followed by water leaching.

J Hazard Mater 2019 Apr 2;374:83-91. Epub 2019 Apr 2.

School of Minerals Processing and Bioengineering, Central South University, Changsha, Hunan, 410083, China.

Chromium was selectively recovered from ferronickel slag by roasting the slag with addition of NaO, followed by water leaching. The thermodynamic analysis revealed that in the presence of NaO at appropriate temperatures, the CrO in the ferronickel slag can be converted to NaCrO, instead of NaCrO, which prevents the formation of highly toxic Cr (VI). The experimental results confirmed that under the optimal alkaline roasting and water leaching conditions of the mass ratio of ferronickel slag to NaO of 1, roasting temperature of 600 °C, roasting time of 1 h, leaching temperature of 50 °C, leaching time of 1 h, and liquid-to-solid ratio of 10 mL/g, 92.

A hierarchical structured steel mesh decorated with metal organic framework/graphene oxide for high-efficient oil/water separation.

J Hazard Mater 2019 Apr 2;373:725-732. Epub 2019 Apr 2.

State Key Laboratory of Petroleum Pollution Control, China University of Petroleum, Qingdao 266555, Shandong, PR China; School of Materials Science and Engineering, China University of Petroleum, Qingdao 266580, Shandong, PR China; State Key Laboratory of Heavy Oil Processing, China University of Petroleum, Qingdao 266555, Shandong, PR China. Electronic address:

A hierarchical structured steel mesh decorated with metal organic framework (UiO-66-NH) nanoparticles/graphene oxide (GO) nanosheets was successfully prepared via a simple self-assemble method. Because water molecules tend to build hydrogen bonds with the amine, carboxyl and hydroxyl functional groups of UiO-66-NH/GO hierarchical structure, the hierarchical structure can easily capture water and tightly lock the water to build a stable water layer on the steel mesh surface and block oil in contact with the steel mesh. Therefore, the obtained hierarchical structured steel mesh exhibits super-hydrophilicity, underwater super-oleophobicity, excellent oil resistance and outstanding oil/water separation performance with a superior high permeating flux (54,500 L m  h) and rejection (>99.

Carbon sources mediate microbial pentachlorophenol dechlorination in soils.

J Hazard Mater 2019 Mar 26;373:716-724. Epub 2019 Mar 26.

Guangdong Key Laboratory of Integrated Agro-environmental Pollution Control and Management, Guangdong Institute of Eco-environmental Science & Technology, Guangzhou, 510650, PR China. Electronic address:

In this study, experiments were performed using network analysis to investigate the effects of different carbon sources, including blank, citrate, glucose and lactate, on indigenous bacterial communities and on the pentachlorophenol (PCP) dechlorination in two soils. Kinetics results demonstrate that PCP dechlorination is significantly enhanced by adding citrate/lactate, but to a lesser extent by adding glucose. High-throughput sequencing results revealed that Firmicutes and Proteobacteria were the dominant groups in these four different treatments during the PCP dechlorination, whereas random forest analysis indicated that the orders Clostridiales, Haloplasmatales, Bacillales, Pseudomonadales and Gaiellales were the critical bacterial orders in modules that were significantly correlated with PCP dechlorination.
