Determination of mercury in organic mercury fungicides by the dithizone method

A modified method for the determination of organic mercury in biota [great cormorants (phalacrocorax carbo)] by advanced mercury analyzer

Background: Contagion of aquatic ecosystems to heavy metals especially mercury (Hg) has risen concerns about healthiness of marine organisms. Organic mercury compounds are highly toxic for animals, and its detection in various samples is frequently needed. In present study we have described a new method for measurement of organic mercury and total mercury concentration in great cormorants (ph...

Determination of mercury at a dithizone-modified glassy carbon electrode by anodic stripping voltammetry.

Determination of mercury (II) by spectrophotometric method based on self assembly of gold nanoparticles

Due to the binding of the –COO- group with the mercury (II), gold nanoparticlesfunctionalized with glutathione can self-assemble to form a supermolecular network in the HAc-NaAc buffer solution. The aggregation of functionalized gold nanoparticles and mercury (II)caused the shift of maximum absorption peak of the UV-Vis spectrum from 520 nm to 609 nm.Based on this principle, a simple spectropho...

Simple Detection of Mercury Ion Using Dithizone Nanoloaded Membrane

The simple Hg(II)-detection system was studied and developed using dithizone nanofiber loaded membrane. Dithizone is one of the most frequently used chemical substances for Hg(II) ions extraction in water. Hg(II)-dithizone complex substance [Hg(HDith)2] is stable in acidic condition and, presenting with the orange-brown color. To prepare dithizone nanoloaded membrane, dithizone solution (in ace...
