چکیده

Catechol-type chitosan resin and salicylic acid-type chitosan resin were easily synthesized for use in estimating the adsorption behavior of 34 elements at pH 1 - 7 in aquatic media. The catechol-type chitosan resin could adsorb Cu(II) at pH 3 - 7, In(III) at pH 4 - 6, Pb(II) and lanthanoids at pH 5 - 7, and U(VI) at pH 4 - 7 more effectively than the salicylic acid-type chitosan resin and the cross-linked chitosan resin (base material). Adsorption ability was in the order: catechol-type chitosan resin > salicylic acid-type chitosan resin > cross-linked chitosan resin.

The Effect of Modified Starch Based Fat Replacer on Milk Properties

In this study, modified starch was used as a fat replacer in the milk. The fat replacer was manufactured from modified starch such as pre-gelatinized and cross–linked starches. Modified starches were manufactured by hydrochloric acid and citric acid treatments from potato and wheat and were added to skim milk at concentrations of 0.15%, 0.30% and 0.45%. Viscosity, total solid, fat content, titr...

Investigation on cross-linked nanomicrobial cellulose properties as modern wound dressing

Background: Nanomicrobial cellulose is an important biopolymer with a three-dimensional structure that is produced by some microorganisms and has been widely used in medicine. One of the unique properties of microbial cellulose is its very high water absorption, which can be used to produce modern wound dressings. But after drying, it’s three-dimensional structure collapses and the amount of wa...
