Anticholinesterase Agents: Poisoning and Treatment01:26

Anticholinesterase Agents: Poisoning and Treatment

1.8K
Anticholinesterases, also known as cholinesterase inhibitors, work by blocking the breakdown of acetylcholine, leading to its accumulation in the synaptic cleft. This accumulation indirectly enhances both muscarinic and nicotinic actions. These agents are classified as reversible or irreversible based on their mechanism of action.     
Irreversible agents form a strong bond with the cholinesterase enzyme, making it inactive. The breakdown of the phosphorylated enzyme is...

Polyprotic Acids03:38

Polyprotic Acids

32.6K
Acids are classified by the number of protons per molecule that they can give up in a reaction. Acids such as HCl, HNO3, and HCN that contain one ionizable hydrogen atom in each molecule are called monoprotic acids. Their reactions with water are:

Aryldiazonium Salts to Azo Dyes: Diazo Coupling01:11

Aryldiazonium Salts to Azo Dyes: Diazo Coupling

3.8K
The reaction of weakly electrophilic aryldiazonium (also called arenediazonium) salts with highly activated aromatic compounds leads to the formation of products with an —N=N— link, called an azo linkage. This reaction, presented in Figure 1, is known as diazo coupling and occurs without the loss of the nitrogen atoms of the aryldiazonium salt. Highly activated aromatic compounds such as phenols or arylamines favor the diazo coupling reaction. The coupling generally occurs at the para...

Adaptations that Reduce Water Loss01:57

Adaptations that Reduce Water Loss

28.4K
Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.

Atomic Absorption Spectroscopy: Interference01:25

Atomic Absorption Spectroscopy: Interference

2.2K
Interference leads to systematic error in atomic absorption (AA) measurements by enhancing or diminishing the analytical signal or the background. These interferences can be grouped into three main categories: spectral interference, chemical interference, and physical interference.
Spectral interference occurs when signals from other elements or molecules overlap with the analyte signal, falsely elevating or masking the analyte's absorbance. This interference can be corrected using Zeeman,...

Bioactivation and Tissue Toxicity01:25

Bioactivation and Tissue Toxicity

71
Bioactivation is a metabolic process that transforms less reactive substances into highly reactive metabolites, initiating tissue toxicity. This transformation can lead to various toxic effects, including carcinogenesis and teratogenesis. Reactive metabolites are classified into two main types: electrophiles and free radicals.Electrophiles are electron-deficient species and are produced primarily by the enzyme cytochrome P-450 during the metabolism of compounds containing carbon, nitrogen, or...

Area of Science:

  • Environmental Chemistry
  • Green Chemistry
  • Organic Chemistry

Background:

  • Atrazine is a widely used herbicide with significant environmental persistence.
  • Developing efficient and environmentally friendly methods for atrazine remediation is crucial.
  • Ascorbic acid (AA) is a potential reductant for organic pollutant degradation.

Purpose of the Study:

  • To investigate the degradation efficiency and mechanism of atrazine using ascorbic acid.
  • To determine the influence of pH on atrazine degradation by ascorbic acid.
  • To elucidate the degradation pathways and intermediates of atrazine under varying pH conditions.

Main Methods:

  • Systematic investigation of atrazine degradation by ascorbic acid at different pH values (4-12).
  • Analysis of degradation intermediates using liquid chromatography-mass spectrometry (LC-MS) and high-performance liquid chromatography (HPLC).
  • Quantification of chloride ions using ion chromatography to confirm dechlorination.

Main Results:

  • Atrazine degradation by ascorbic acid was observed across a broad pH range (4-12).
  • Degradation efficiency was higher under acidic (pH≤4) and alkaline (pH≥12) conditions compared to neutral pH (pH=7).
  • Dechlorination of atrazine was confirmed, with maximum efficiency at pH 12, even in the absence of molecular oxygen. More degradation products were observed at alkaline conditions.

Conclusions:

  • Ascorbic acid is an effective agent for atrazine degradation, with pH significantly influencing the efficiency.
  • The study elucidates the pH-dependent degradation mechanism and pathways of atrazine induced by ascorbic acid.
  • Findings support the potential application of ascorbic acid for the remediation of atrazine and similar organic pollutants.
