The last three steps of the alginate production process were studied:conversion of alginic acid to sodium alginate, drying, and milling. Threemethods were used to follow the conversion reaction: measuring the pH (a) ...

Three steps of the alginate production process were studied at pilot plantlevel. The effect of the amount of calcium chloride used during theprecipitation was measured in terms of filtration time of the precipitatedcalcium ...

The marine waters of the Baja California peninsula (Mexico) are a rich source of brown seaweeds with a great potential for exploitation. For that reason, Sargassum sinicola, Eisenia arborea, and Macrocystis pyrifera collected ...

Oxidation reactions on -OH groups at C-2 and C-3 positions of the uronic units of sodium alginate were performed with sodium periodate, and the influence of degree of oxidation on physical properties of the oxidized ...

Ionic liquids (ILs) were examined as new components in polymer/IL mixtures for their potential applications as advanced materials. This work reports the thermodynamics of the aggregation of imidazolium ionic liquids, CnMIMBr ...

Polymeric hydrogels are important biomaterials with potential for various applications including the controlled release of drugs. Clay and zeolite nanostructures can enhance the absorption and release properties of hydrogels. ...

In this study, we proposed the use of the biopolymer alginate to produce membranes with diclofenac sodium incorporated as model-drug aiming at wound dressing application with drug delivery. The membranes were prepared by ...
