Chitosan and alginate biopolymer membranes for remediation of contaminated water with herbicides
(Elsevier B.V., 2013-12-15)
This study investigated the adsorption behavior of the herbicides diquat, difenzoquat and clomazone on biopolymer membranes prepared with alginate and chitosan (pristine and multi-layer model) for contaminated water ...
Studies on the formation of complex coacervates between chitosan and alginate during microparticles preparation
(2005-07-01)
The formation of complex coacervates between chitosan and alginate was evaluated during microparticles formation. Mass ratio between polyelectrolytes and calcium chloride concentration were determinated by conductimetric ...

Microspheres of alginate-chitosan containing isoniazid
(Taylor & Francis Ltd, 2003-01-01)
Isoniazid was encapsulated into microspheres of alginate-chitosan by means of a complex coacervation method in an emulsion system. Since the encapsulation of isoniazid tends to be limited by its hydrophilic characteristics, ...

Comparative studies on polyelectrolyte complexes and mixtures of chitosan-alginate and chitosan-carrageenan as prolonged diltiazem clorhydrate release systems
(ELSEVIER SCIENCE BV, 2004-01)
The aim of this work was to evaluate the possibility of using mixtures and/or polyelectrolyte complexes from both chitosan-alginate and chitosan-carrageenan as prolonged drug release systems. Different dissolution profiles ...
