    Abstract: A process for effecting flame retardation of fibrous structures, such as fabrics, particularly fabrics made from mixtures of natural and synthetic fibers, such as cotton and nylon. The process includes the steps of contacting the fabric to be treated with halomonomers and/or inorganic salts, followed by fluorocarbon grafting, and then by photohalogenation. The aforesaid treatment results in fabrics which are not only flame resistant but also have improved hand, manifested by softness, silkiness, and unwettability of the resulting fabric.

    Abstract: A method is provided for detecting the presence of organic materials in an aqueous sample. The materials are decomposed by simultaneous exposure to ultraviolet radiation and acoustic energy to decompose the materials to simple decomposition products. The simple decomposition products such as ammonium ion, halogen ion, alkyl ammonium ions, or sulfate ions, are then detected by conventional analytical devices and methods.
