The effect of chlorine on mercury oxidation and nitrogen oxides (NO x ) reduction over selective catalytic reduction (SCR) catalysts was investigated in this study. Commercial SCR catalysts achieved a high Hg0 oxidation efficiency when Cl2 was sprayed into the flue gas. Results indicated that an appropriate concentration of Cl2 was found to promote...

A novel carbon-based sorbent was prepared from FeSO4-flocculated sludge by one-step pyrolysis. The characterization results indicated that multiple Fe2O3 and sulfur species (S2²⁻ and polysulfide) existed over this sludge-derived sorbent. Its performance on Hg⁰ removal from syngas was evaluated. The sorbent from the sludge pyrolyzed at 710 ℃ could a...

By the pyrolysis of Fe-containing sewage sludge activated with sulfuric acid, a magnetic and sulfur-resistant sorbent (FSS-SA) was obtained, and it was used for capturing elemental mercury from flue gas. Sulfuric acid activation improved the pore structure, increased the contents of Fe³⁺, Oβ and polysulfide and promoted the redox activity of the so...
Article
In this work, sewage sludge flocculated with ferrous sulfate (SFS) was treated by one-step pyrolysis and ZnCl2 activation to obtain magnetic Fe-containing carbon, which was used to remove elemental mercury (Hg⁰) from flue gas. When 30% ZnCl2 was added to SFS (names as SFS-30), sulfides, chloride, magnetic FexOy, as well as a suitable BET surface ar...

Mercury pollution has become one of the most concerned environmental issues in the world because of its high toxicity, non-degradability and bioaccumulation. Attapulgite adsorbents modified by magnetic manganese-copper (Mn x Cu y -MATP) were fabricated by co-precipitation and ultrasonic impregnation method,aiming at removing Hg ⁰ from coal-fired fl...
Article
Although individual toxicity of microplastics (MPs) to organism has been widely studied, limited knowledge is available on the interactions between heavy metals and MPs, as well as potential biological impacts from their combinations. The interaction between MPs and heavy metals may alter their environmental behaviors, bioavailability and potential...

Alzheimer’s disease (AD) is one of the most common neurodegenerative diseases. The association between environmental factors (e.g., pesticide) and AD has attracted considerable attention. However, no systematic analysis has been performed and make it difficult to provide deeper insights of AD correlated with pesticide exposure. Hence, this study ut...

A novel biochar containing highly-dispersed cobalt oxides was prepared by one-step pyrolysis using Co-enriched Siberian Iris as the raw material, and it was used for elemental mercury removal from flue gas. The presence of NO or HCl could approximately keep Hg⁰ removal efficiency over 85%, while the presence of SO2 suppressed Hg⁰ removal. The role...

A growing body of evidence suggests that the lip products are polluted by heavy metals, which would inevitably cause safety problems with long-term exposure, but few studies have focused on their deeper health risk assessments. This study sets out to identify the lip cosmetics in good sale from Chinese e-commerce market utilizing Python crawler and...

The sewage sludge flocculated with ferrous sulfate (SFS) was prepared by one-step pyrolysis to obtain magnetic Fe-containing carbon. Results showed that only a small amount of FexOy as well as extremely weak magnetism were observed at pyrolysis temperatures of less than 500 °C. SFS tended to exhibit intensive agglomeration, leading to the drastic i...
