Controlled release formulations of carbaryl based on copper alginate, barium alginate, and alginic acid beads
(John Wiley & Sons Inc, 2006)A controlled release system for reducing environmental impact was produced by encapsulating the pesticide carbaryl (Carb) in the alginate beads. The various bead formulations were prepared by using sodium alginate (NaAlg) ... -
Controlled release of aldicarb from carboxymethyl cellulose microspheres: in vitro and field applications
(John Wiley & Sons Ltd, 1999)Aldicarb is a carbamate pesticide that is widely used throughout the world in the protection Of crops (eg cotton, nuts, potatoes, onion, tobacco, sugar beet and sugar cane). In Turkey, especially in the Cukurova region, ... -
Controlled release of aldicarb from lignin loaded ionotropic hydrogel microspheres
(Taylor & Francis Ltd, 1999)Aldicarb loaded microspheres of carboxymethyl cellulose, CMC, of various compositions were prepared with the crosslinking action of AI(III). Into these microspheres, lignin was introduced as a filler to further regulate ... -
Controlled release study of carbaryl insecticide from calcium alginate and nickel alginate hydrogel beads
(Wiley, 2007)In this study, controlled release formulations for reducing environmental impact of pesticides have been produced by encapsulating as a model pesticide carbaryl (Carb) in the alginate beads. The various hydrogel bead ... -
Fluoride release from microporous poly(2-hydroxyethyl methacrylate) membranes
(Elsevier Science Bv, 2003)Fluoride ion is commonly used in the preventive treatment of tooth decay and when provided with extra fluoride, children living in regions that lack fluoride benefit from it. In the present study, the clinical properties ... -
In vitro release study of diltiazem hydrochloride from poly(vinyl pyrrolidone)/sodium alginate blend microspheres
(Wiley, 2008)Polymeric blend microspheres of poly(vinyl pyrrolidone) (PVP) with sodium alginate (NaAlg) were prepared by cross-linking with calcium ions and used to deliver a calcium channel blocker drug, diltiazem hydrochloride (DT). ... -
Release characteristics of diclofenac sodium from poly(vinyl alcohol)/sodium alginate and poly(vinyl alcohol)-grafted-poly(acrylamide)/sodium alginate blend beads
(Elsevier, 2007)In this study, acrylamide (AAm) was grafted onto poly(vinyl alcohol) (PVA) with UV radiation at ambient temperature. The graft copolymer (PVA-g-PAAm) was characterized by using Fourier transform infrared spectroscopy (FTIR), ... -
Synthesis and characterization of poly(N-Vinyl-2-pyrrolidone) grafted sodium alginate hydrogel beads for the controlled release of indomethacin
(Wiley, 2008)Graft copolymers of sodium alginate (NaAlg) with N-vinyl-2-pyrrolidone were prepared using azobisisobutyronitrile as initiator. The graft copolymers (NaAlg-g-PVP) were characterized with Fourier transform infrared spectroscopy, ...
