Present paper is an attempt to remove a hazardous dye, tartrazine by using hen feathers as adsorbent. Using poly3hexylthiophene, we demonstrate surfactantfree synthesis and characterization of sizecontrolled, semicrystalline polymer. We report a highyield synthetic method for a new type of metal nanostructure, spiky gold nanoshells, which combine the morphological characteristics of hollow metal nanoshells and nanorods. Langmuir and freundlich isotherms as model for the adsorption of nucleic acid. Langmuir cove, a cove in the north end of arrowsmith peninsula, graham land, antarctica. Maize cob was found to be an excellent adsorbent for the removal of these metal ions. Disadvantages of the model edit the langmuir adsorption model deviates significantly in many cases, primarily because it fails to account for the surface roughness of the adsorbent.
