Sorptions on lignin wood and celluloses ii. nitrosamines

摘要: Abstract Sorption of N -diethylnitrosamine depends very characteristically on the mode preparation lignins. Some enzymatically prepared lignins are strong sorbers, similar to Kraft lignin. Lignins by digesting Hurricane pulverized wood show smaller nitrosamine binding than obtained from treated in Wiley-mill, for a given residual saccharide content. This difference is not due solely iron contents. For comminuted Wiley-mill capacity indirectly proportional sugar -nitrosamine adsorption involves different sites that bile acids. Appearance two some indicates nitrosamines might compete with metal (II) ions. Nevertheless, sorption -nitrosamines accessibility also plays role.
