A term used to define the purity of isolated cellulose according to its solubility in alkali. 1, record 1, English, - alpha%2Dcellulose
Record number: 1, Textual support number: 1 CONT
The alpha-cellulose is that portion of pulp which does not dissolve in 18% aqueous NaOH. The greater the quantity of alpha-cellulose present, the higher the purity of the material. However, alpha-cellulose is not necessarily pure cellulose, since alkali-soluble glycans may still be combined with it. 1, record 1, English, - alpha%2Dcellulose

La cellulose alpha est la fraction de la pâte qui est insoluble dans une solution aqueuse de soude caustique(NaOH) à 18 %. Plus il y a de cellulose alpha, plus la pâte est pure. Cependant, la cellulose alpha n’ est pas nécessairement de la cellulose pure puisqu'elle peut être combinée à d’autres polysaccharides solubles en milieu alcalin. 4, record 1, French, - cellulose%20alpha

Record number: 2, Textual support number: 1 OBS
A high value indicates a strong tendency for adsorption to soil or sediment, rather than remain dissolved in soil solution (or pore water). Strongly adsorbed molecules will not leach or move unless the soil particle to which they are adsorbed moves (as in erosion). Koc of less than 500 indicates little or no adsorption and a potential for leaching. 2, record 2, English, - organic%20carbon%2Dwater%20distribution%20ratio

Le facteur de retard est proportionnel au coefficient de distribution Kd, qui décrit la séparation d’un soluté dissous entre les phases aqueuse et sorbée. Le degré d’adsorption est directement lié au contenu en carbone organique du sol. On sait qu'il existe une relation empirique entre Kd, la fraction massique en carbone organique dans le sol(foc) et le coefficient de distribution carbone organique/eau(Koc) : Kd=foc.
