The enzyme-activated cellulose technology is an ex situ process that was designed to treat contaminated water. Cellulose, coated with a proprietary enzyme, is used to remove metals and organic compounds from an aqueous solution. 

According to the vendor, the cost of implementing the enzyme-activated cellulose technology can reach as low as 0.40 per 1000 gal of contaminated water treated (D140738, p. 52).

Regenerated cellulose fibers are uniform in diameter. This permits a tmiform oxidation and imparts uniform chemical and physical characteristics to the pharmaceutical material. In the early 1960 s, Johnson Johnson entered the market with an oxidized knitted rayon fabric, SURGICEL Absorbable Hemostat. Since then, Johnson Johnson has dev eloped a few other oxidized knitted rayon products. A list of currently av ailable bioabsorbable oxidized cellulose and oxidized regenerated cellulose products, and the respecthe manufacturer is contained in TkdUe 1. A list of relevant patents for oxidized cellulose technology is contained in IkUe 2.

The xanthates, or dithiocarbonates, are important substances in cellulose technology. They have been studied to some extent with the simple sugars. Their sodium salts are formed from the alcohol, carbon disulfide, and alkali and may be converted to the alkyl esters.
