Resin & Carbon

Category: Resin & carbon

*Resin:

The resin produced by most plants is composed mainly of terpenes and derivatives. The most common terpenes in resin are the bicyclic terpenes alpha-pinene, beta-pinene, delta-3 carene, and sabinene, the monocyclic terpenes limonene and terpinolene, and smaller amounts of the tricyclic sesquiterpenes, longifolene, caryophyllene and delta-cadinene. Some resins also contain a high proportion of resin acids. The individual components of resin can be separated by fractional distillation. Rosins on the other hand are less volatile and consist, inter alia, of diterpenes.

 

*Carbon:

Determination of biodegradable dissolved organic carbon in waters is of particular importance for the water treatment industry.
A simple method for determining biodegradable dissolved organic carbon which is applicable to surface and drinking water is proposed.
It consists of sterilizing the water sample,inoculating it with autochthonous bacteria, and measuring the decrease in dissolved organic carbon concentration due to the carbon oxidization by bacteria.
The detailed experimental procedure is discussed,and validation of the method is presented.
The method has been used for studying river waters and for drinking water treatment plant design.
