Cleaner Production in the Process of p-amino azo benzene 4-sulfonic acid
Kinjal Patel, PG student at LDCE, Ahmedabad. Phone:9974407792 E-mail: [email protected] Abstract—The common indicators of economic welfare, such as national product and income have reflected the growth of the industry as a major indicator for the development of the nation. But the other angle of industrialization has been the serious damage to the surrounding environment so there is keen n...
متن کاملDerived Photosensitive Pigments from Invertebrate Eyes
The red pigment in the eyes of the squid, blue crab, and horseshoe crab becomes photosensitive when treated with formalin, and bleaches in the light. The resulting change in density is approximately symmetrical around a maximum at 480 mmicro in the blue green. This difference absorption spectrum is in rough agreement with the spectral sensitivity of the cephalopod eye and differs only slightly ...
متن کاملSupramolecular Electronics Derived from Porphyrin-like Pigments
The field of organic based electronics has become a blossoming area of intensive study during the past decade. The promise of a cheaper and easier-to-process alternative to inorganic based semiconductor materials makes these materials highly desirable. Additionally, organic based electronics can be made into flexible structures, allowing for the fabrication of visual displays that can be folded...
متن کاملHighly Porous Activated Carbons Derived from Poly(styrene Sulfonic Acid) Based Organic Salts
The objective of this paper is to study the effect of transition metals used in organic salts on the structural properties of carbonaceous materials. To accomplish our objectives, we carbonized commercially available poly(styrene sulfonic acid-co-maleic acid), sodium salt. To study the effect of metals, sodium was exchanged with either cobalt, nickel, or iron. Park and Jung [1], and Putyera et ...
متن کاملAzo pigments and quinacridones induce delayed hypersensitivity in red tattoos.
BACKGROUND Induction of delayed hypersensitivity reactions by red tattoos has been occasionally reported. Little is known about the inks used. Azo pigments have been implicated in some instances, but there is only one reported case involving quinacridones. OBJECTIVES To describe the clinical and pathological features and outcome of skin reactions induced by red tattoo pigments. PATIENTS, MA...
