Abstract:   (1954 Views)
In the present study, a new type of an encapsulate pesticide was prepared by Coacervation method. Lambda-Cyhalothrin was encapsulated due to interaction between two oppositely charged materials, gelatin and gum Arabic as shell in a complex Coacevation process at the presence of 10 mol etoxylated nonyl phenol (NPE) which is a kind of a non-ionic emulsifier to enhance the homogenization of the product and size control. Spherical shape of capsules were scanned by Scanning Electron Microscopy (SEM) and optical microscope. The encapsulation efficiency was achieved 96% and analyzed by Gas chromatography equipped with FID detector (GC-FID). From the results of release study, 49, 63, 89% of encapsulated materials were released from their shell after 15, 30,180 min respectively. The present study, applies a convenient and inexpensive method to introduce a pesticide, which can be exploited in public health field.
