The autocatalytic reaction between chlorite and iodide ions exhibits a remarkable range of dynamical behavior. In a stirred tank reactor it shows bistability between steady states and between a steady and an oscillatory state. It forms the core of a large family of systematically designed chemical oscillators. The chlorite-iodide system has served as the prototype reaction in the discovery and ...

Ten chromite ores from ophiolite complexes in SE Iran were analyzed mineralogically by XRD, chemically by XRF, and mineral chemistry by EPMA. The identified paragenesis of silicate minerals of chromite ores with the X-ray diffraction is pronounced differently. It consists of secondary phases formed as serpentine, Cr-containing chlorite (kaemmererite), chromic garnet (uarovite) with preserved pa...

Remote sensing plays an important role in mineral exploration. One of its proven applications is extracting host-rock lithology and alteration zones that are related to porphyry copper deposits. An Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) was used to map the Baogutu porphyry deposit alteration area. A circular alteration mineral zoning pattern was clearly observed ...

the presence of microbial load and high fiber content in various non conventional feedstuffs limit their utilization in poultry feed. in the present study, the feedstuffs were treated with acidified sodium chlorite (asc) and its impact on  the microbial load and metabolizable energy availability was assessed in  the chickens. the effect of supplementation of feed grade enzyme was also evaluated...

indicates how intermediates between mica and chlorite might be formed. Giving Mand B+ the representative compositions [MgsAlSi301o(0H)2] and [Mg2Al(0H)e]+, the intermediate shown would have the composition KMg8AlsSi6020(0H)1o, and would have an effective interplanar distance on (001) of 24.3 A., just the sum of those for mica and chlorite. Chloritebrucite intermediates would probably be unstabl...

A new clock reaction based on chlorate, iodine and nitrous acid is presented. The induction period of this new clock reaction decreases when the initial concentrations of chlorate, nitrous acid and perchloric acid increase, but it is independent on the initial iodine concentration. The proposed mechanism is based on the LLKE autocatalytic mechanism for the chlorite-iodide reaction and the initi...

This study was undertaken to investigate the effect of retting method on molecular weight different portion Agave atroverance fiber (top, middle and bottom) extracted by techniques. The raw fibers from plant were retted biological chemical (degumming) methods. In both stagnant boil water utilized in method, fibres treated with 5% NaOH. is not purely cellulosic fiber. Percentage composition also...
