An X-ray photoelectron spectroscopy confirmed that the percent of graphitic N in SDBC decreased after the degradation reaction, which suggested graphitic N is an important active site in biochar. Besides, acid-washed SDBC did not change TC degradation behavior excluding significant contribution of ...
Biochar is a well-known material for pollutant removal owing to its low cost and rich surface functionality. A kind of highly active substance, called environmentally persistent free radicals (EPFRs), can be produced in the preparation process of biochar, playing an important role in the removal...

Here, we propose a low-cost, sustainable, and viable adsorbent (pine tree-derived biochar) to remove acid dyes such as acid violet 17 (AV), which is used i... E Sterenzon,VK Vadivel,Y Gerchman,... 被引量: 0发表: 2021年 加载更多来源...
Sludge pyrolysis can convert approximately half of the organic matter in sewage sludge into renewable liquid fuels and chemical feedstock, and immobilize the remainder and the inorganic matter into a stabilized form of pyrolytic residue (biochar)21,22. This residue, a carbonaceous matrix byproduct ...
Influence of pyrolysis temperature on physical and chemical properties of biochar made from sewage sludge Cd, As, Cu and Cr in the biochars was lower than that in the sewage sludge although the pyrolysis process enriched the heavy metals in the biochars... H Yuan,L Tao,H Huang,... - 《J...
In turn, SS-derived biochar was enriched in N% (3.29–3.76%), whereas lowered in C% Conclusions Conversion of bio-wastes to biochar can solve the problem of their utilization especially when toxic sewage sludge was used. Biochar used in the environment will chemisorb FA in different extend. ...
Ball-milling paper sludge biochar (Fe-MSDBC) was prepared for persulfate (PDS) activation.The tetracycline (TC) adsorption removal of Fe-MSDBC could be up to 80.7%.Fe-MSDBC efficiently activated PDS for TC removal (96.4%).OH was the major radical and was responsible for TC removal.The Fe...
Sulfurized biochar derived from sewage sludge (SSB) was facilely synthesized and manifested upgraded performance in activation of peroxymonosulfate (PMS) and peroxydisulfate (PDS) for bisphenol A (BPA) elimination. The incorporated zigzag-edge sulfur effectively activated the sp-hybridized graphene lattice...
