AI Article Synopsis

  • Arsenic species are toxic to humans, prompting the need for effective removal methods from contaminated water sources.
  • This study developed bismuthene quantum dots (Bi-ene-QDs) using a simple green hydrothermal reaction, which showed a size of 6.0 nm and high surface area for adsorption.
  • Bi-ene-QDs demonstrated over 94% efficiency in capturing As(V) ions from various water types, making them a promising solution for tackling arsenic pollution in wastewater.

Article Abstract

Arsenic species have been known for their toxic impact on human. Therefore, removal of such pollutant requires efficient and effective removal methodology from polluted water. In this study, bismuthene quantum dots (Bi-ene-QDs) were fabricated by a green and facile one pot-hydrothermal conversion reaction of Bi(NO)·5HO. Bi-ene-QDs exhibited semi-spherical crystalline providing 6.0 nm 157.78 m/g. Consequently, As(V) capturing by Bi-ene-QDs revealed optimum practical conditions at pH 3, interaction duration time 40 min and 10 mg Bi-ene-QDs dosage. The interaction of As(V) ions with Bi-ene-QDs were confirmed by the appearance of As-O stretching vibration. Moreover, Bi-ene-QDs achieved excellent adsorptive capture percentages of Arsenic ions from sea, tap and wastewater providing 94.61, 95.21 and 94.38% from contaminated samples with 5 mg L Arsenic ions. Therefore, Bi-ene-QDs can be categorized as an unprecedented and efficient nanosorbent for the successful removal of Arsenic ions pollution from various wastewater matrices with > 90.0% efficiency.

CesA proteins response to arsenic stress in rice involves structural and regulatory mechanisms, highlighting the role of BES1/BZR1 transcript levels under arsenate exposure and significant downregulation of BZR1 protein expression. Plants interact with several hazardous metalloids during their life cycle through root and soil connection. One such metalloid, is arsenic and its perilous impact on rice cultivation is a well-known threat.

The optical detection of arsenic (As) in human biological fluids and environmental water samples is presented using alpha-cyclodextrin-modified silver nanoparticles (α/CyD-AgNPs) at the trace level. This method is based on the measurement of a red shift of the LSPR band of α/CyD-AgNPs in the region of 200-800 nm. The color of α/CyD-AgNPs was changed from yellow to colorless by the addition of As(iii).

Developing highly efficient bimetallic metal-organic frameworks (MOFs) as catalysts for Fenton-like reactions holds significant promise for decontamination processes. Although MOFs with excellent decontamination capabilities are achievable, ensuring their long-term stability, especially in the organoarsenic harmless treatment, remains a formidable challenge. Herein, we proposed a unique nanoconfinement strategy using graphene oxide (GO)-supported Prussian blue analogs (PBA) as catalytic membrane, which modulated the peroxymonosulfate (PMS) activation in p-arsanilic acid (p-ASA) degradation from traditional radical pathways to a synergy of both radical and non-radical pathways.
