Decontamination of Cr(VI) facilitated formation of persistent free radicals on rice husk derived biochar

Kaikai Zhang, Peng Sun, Yanrong Zhang

Frontiers of Environmental Science & Engineering 2019, Volume 13, Issue 2, doi: 10.1007/s11783-019-1106-7

Abstract:

PFRs were produced on biochar during Cr(VI) decontamination.

PFRs formation on biochar was owing to the oxidization of phenolic-OH by Cr(VI).

Appearance of excessive oxidant led to the consumption of PFRs on biochar.

Biochar charred at high temperature possessed great performance to Cr(VI) removal.

Keywords： Biochar     Persistent free radicals     Phenolic hydroxyl groups     Cr(VI) reduction

Frontiers of Environmental Science & Engineering 2015, Volume 9, Issue 5,   Pages 905-911 doi: 10.1007/s11783-015-0786-x

Abstract: nano-silicon (Si) and common Si on lead (Pb) toxicity, uptake, translocation, and accumulation in the riceThe results showed that Si application alleviated the toxic effects of Pb on rice growth.Pb concentrations in rice grains treated with common Si and nano-Si decreased by 21.3%–40.9% and 38.6%growth, preventing Pb transfer from rice roots to aboveground parts, and blocking Pb accumulation inrice grains, especially in high-Pb-accumulating rice cultivars and in heavily Pb-polluted soils.
