Application

Tin(II) chloride dehydrate may be used:

As a reducing agent for the determination of hydride forming species by AAS.
In the conversion of organomercurials into inorganic mercury determined using a flow injection-cold vapor atomic absorption spectrometry
In the determination of total mercury content, using atomic fluorescence spectroscopy and mercury speciation was performed using gas chromatography inductively coupled plasma mass spectrometry (GC-ICPMS).

General description

Tin(II) chloride dehydrate converts conjugated dioxolones to aldehyde. It helps as a catalyst in multi-component condensation reaction from aromatic aldehydes, 2-aminopyridines and isonitriles which results in reasonable yield and reducing the reaction time.

Room temperature sonolysis-based advanced oxidation process for degradation of organomercurials: application to determination of inorganic and total mercury in waters by flow injection-cold vapor atomic absorption spectrometry

Capelo et al.

Analytical chemistry, 72(20), 4979-4984 (2000-10-31)

A new oxidation method based on room-temperature ultrasonic irradiation (sonolysis) is proposed for conversion of organomercurials into inorganic mercury and subsequent determination by flow injection-cold vapor atomic absorption spectrometry. This advanced oxidation process eliminates the need for chemical oxidants, high

The Zn-Sn nanoparticles/multiwall carbon nanotubes (Zn-SnNPs/MWNTs) nanocomposite film was prepared by electrodeposition of ZnCl(2) and SnCl(2) on MWNTs simultaneously in Ethaline ionic liquids. Then, based on immobilizing hemoglobin (Hb) within a novel Zn-SnNPs/MWNTs nanocomposite film (Hb/Zn-SnNPs/MWNTs), a novel hydrogen peroxide
