Adsorption of sodium alginate onto sodium montmorillonite

Materials Today: Proceedings, 2021
Abstract The interactions between polymers such polysaccharides and clay can be controlled by different factors, such as the functional groups of the polymers, pH and salinity of the suspension. This study was conducted to understand the various kinds of interactions between sodium Alginate (NaAlg) a polyanion negatively charged and sodium ...

Study of electrospinning of sodium alginate, blended solutions of sodium alginate/poly(vinyl alcohol) and sodium alginate/poly(ethylene oxide)

Journal of Applied Polymer Science, 2007
AbstractAlginate is an interesting natural biopolymer for many of its merits and good biological properties. This paper investigates the electrospinning of sodium alginate (NaAlg), NaAlg/PVA‐ and NaAlg/PEO‐ blended systems. It was found in this research that although NaAlg can easily be dissolved in water, the aqueous NaAlg solution could not be ...

Modification ofα-Amylase by Sodium Alginate

Acta Biotechnologica, 2001
Sodium alginate, activated by periodate oxidation, was covalently linked to porcine pancreatic α-amylase via reductive alkylation with NaBH4. The enzyme-polymer conjugate, purified by gel filtration on Fractogel EMD BioSEC (S), retained about 50% of the native specific amylolytic activity.

The depolymerization of sodium alginate by oxidative degradation

Pharmaceutical Development and Technology, 2011
Alginate has been extensively used as a carrier for macromolecules and as gene delivery vehicle. Both properties are molecular weight (Mw) dependent. Herein, we investigated factors affecting the oxidative depolymerization of alginate. The depolymerization process occurred mainly in the first 1 h.

Sodium Alginate Toughening of Gelatin Hydrogels

ACS Biomaterials Science & Engineering, 2017
Gelatin is a popular material for the creation of tissue phantoms due to its ease-of-use, safety, low relative cost, and its amenability to tuning physical properties through the use of additives. One difficulty that arises when using gelatin, especially in low concentrations, is the brittleness of the material.

Microencapsulation of oils using sodium alginate

Journal of Microencapsulation, 2000
The feasibility of encapsulating wheatgerm oil and evening primrose oil using sodium alginate by the emulsification method was explored in this study. It is based on the chemical reaction between the water-soluble sodium alginate and polyvalent cation, calcium, to form the water-insoluble alginate.

Pharmacobezoar complicating treatment with sodium alginate

Journal of Gastroenterology, 2004
We encountered a gastric bezoar that had developed in a 9-year-old girl treated with sodium alginate (Alloid G) for acute gastritis associated with systemic lupus erythematosus. A hard mass palpated in the left upper abdomen proved, upon gastric endoscopy, to be an intragastric foreign body.

Dietary effects of sodium alginate in humans

Food Additives and Contaminants, 1991
Following a 7-day control period, five male volunteers consumed a weight of sodium alginate corresponding to 175 mg/kg body weight for 7 days, followed by 200 mg sodium alginate per kg body weight for a further 16 days. Measurements before and at the end of the 23-day period of dietary supplementation showed that sodium alginate acted as a faecal ...

Complex Coacervation of Milk Proteins with Sodium Alginate

Journal of Agricultural and Food Chemistry, 2018
Beta-lactoglobulin (BLG) and bovine serum albumin (BSA) coacervate formation with sodium alginate (ALG) was investigated by turbidimetric analysis, zeta potential, particle size, viscosity, transmission electron microscopy (TEM) and isothermal titration calorimetric (ITC) measurements as a function of pH (1.0-7.0) and protein/alginate mixing ratio (1:1,

UHMWPE Modified Sodium Alginate

Materials Science Forum, 2015
Aim of our experiments was to modify prosthetic material UHMWPE powder using sodium alginate. The sodium alginate has an important property that the appropriate chemical reagent could exchange its Na+ions to Ca2+ions. The Ca has important role in the healing process, so modifying this substance the UHMWPE material helps patients healing.
