TLDR
Polyurethane foam as a novel support for immobilization of horseradish peroxidase has been used for the development of a test technique for the determination of trace organomercury cations based on their liberating effect on the enzyme inhibited by phenylthiourea in the o-dianisidine oxidation.About:

Determination of organic mercury species in soils by high-performance liquid chromatography with ultraviolet detection
TL;DR: Reversed-phase high-performance liquid chromatography with ultraviolet detection was optimized for the simultaneous separation and quantification of nine organic mercury compounds: methyl-, ethyl-, phenyl-, methoxyethyl, ethoxyethyl-, benzoic and tolylmercury, mersalylic acid and nitromersol.

Evaluation, mechanism and application of solid-phase extraction using a dithiocarbamate resin for the sampling and determination of mercury species in humic-rich natural waters
TL;DR: In this article, a method for the simultaneous determination of mercury species at sub-ng l-1 levels in humic-rich natural waters was evaluated, and the model derived indicated that the rate-determining step for collection of the mercury species is the release of these species from two major groups of sites present on the humic substances.
