Definitions
- thiuram compounds are added to latex in two batches, i. e. once before the sale of latex to the manufacturers and once after the sale. In some instances, the amount of thiuram compounds added to a rubber product may exceed the acceptable amount of thiuram compounds for producing optimal manufactured product properties. With an overloading of thiuram compound in a rubber product, the rubber product usually possesses poor product quality and manufacturers may also suffer losses due to burnt rubber and over vulcanization.
- a volume of latex or latex product to be tested is extracted and transferred or placed into a suitable container (e.g., a test tube).
- a suitable container e.g., a test tube.
- a volume of latex or latex product which contains about 4( ⁇ g to 40( ⁇ g of thiuram compounds can be used for testing.
- the amount of thiuram compounds in the latex or latex product is unknown, 0.001 g to 1.000 g or 1 to 20 drops (for example, 10 drops) of latex or latex product can be used.
- An optical property of the coloured complex layer can be used for determining or estimating the amount of copper (Il)-fhiuram complex.
- one or more optical properties of the coloured layer such as hue, colour intensity, a chromatic characteristic, or absorption at one or more wavelengths can be correlated to the amount of copper (II)- thiuram complex present in the coloured layer. Since the amount of copper (Il)-thiuram complex present in the coloured layer represents the amount of thiuram compounds that are present in the latex sample, determination or estimation of the concentration of copper (Il)-thiuram compounds in the complex layer can serve as an indicator of the concentration of thiuram compounds present in the latex sample.
- the copper (Il)-thiuram complex has to be of a certain minimum concentration to present itself as an observable layer. For instance, a clear yellow solution can only be observed with naked eye if the copper (Il)-thiuram complex solution is at least 20mg/mL or 20 ⁇ ,. Hence, depending on the volume of latex or latex product sample used for testing and the corresponding amount of thiuram compounds present in the latex or latex product sample, the amount of thiuram compounds present in the test sample may not be adequate for forming complexes with copper (II) ions to create an observable layer.
- TMTD TMTD
- TMTD a toxic substance
- protective gloves and a mask are worn while handling TMTD.
- the test tubes are topped up with pure water such that the content of each of the test tubes has a volume of 10.0 millilitres.
- Each of the test tubes is subsequently agitated for at least 1 minute.

Abstract
La présente invention a pour objet différents kits et procédés d'analyse pour la détermination ou l'estimation d'une quantité d'un composé thiurame dans un échantillon de latex ou de produit de latex. Dans un mode de réalisation, un procédé de détermination comprend les étapes consistant à mettre en contact un échantillon avec (1) une solution complexante contenant des ions cuivre (II) qui peuvent former des complexes avec les composés thiurame dans l'échantillon ; et (2) une solution de différenciation contenant un composé qui peut extraire un composé cuivre (II) - thiurame. La mise en contact de l'échantillon avec la solution complexante et la solution de différenciation entraîne la formation d'un mélange ayant une première et une seconde couche de densités différentes. Une propriété optique (par exemple la couleur) de la couche de densité inférieure correspond à une quantité de composés thiurame dans l'échantillon ; la quantité de thiurame dans l'échantillon peut donc être déterminée ou estimée. Dans certains modes de réalisation, le protocole d'analyse comprend la préparation d'une série de solutions diluées ayant une concentration connue destinées à être utilisées en tant que solutions de référence.
