Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Air quality study during the survey revealed that the ambient air was contaminated by fluorides. Constant emission of gases by the industry had led to a large scale deposition of fluoride particles on the fodder and leaves of crops. The fluoride concentration in fodder and plant samples varied from season to season and with respect to distance and direction from the fluoride source. NE area was more contaminated than the other areas like SE, SW and NW. Dental survey of children (age 6 to 13.5 years) revealed that near the factory, in villages like Bhestan and Dindoli dental lesions were more common than in those for away from the industry. Estimation of human urine samples of the area, indicates higher level of fluoride than the average value with a highest value of 12 ppm. All cattles are more or less affected all the villages surveyed. High level of fluoride was noted in urine and bone of cattles residing in the immediate surroundings of the factory. The survey indicates that the concentration of pollutant is higher than emission standards or standards for occupational health. 160 pp. Englisch.…

Taschenbuch. Condizione: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - El presente estudio se llevó a cabo para evaluar la pérdida por corrosión del metal de zinc en diversas concentraciones de ácido nítrico y para la protección del metal de zinc se utilizaron aminas aromáticas (toludinas, nitroanilinas, cloroanilinas) y aminas alifáticas (etanolaminas, etilaminas). La pérdida de corrosión del zinc aumenta con el incremento de toda la concentración de ácidos. La pérdida por corrosión se ve afectada por la presencia de oxígeno de difusión, la naturaleza de la reacción compleja que tiene lugar y también la naturaleza de la película protectora. La eficiencia de la inhibición se incrementó en todas las aminas aromáticas estudiadas en todos los inhibidores de los inhibidores con el aumento del ácido. En todos los tipos de aminas aromáticas o-cloro anilina, la m-nitroanilina ha demostrado ser un excelente inhibidor. En todas las aminas alifáticas, la etanolamina ha demostrado ser un excelente inhibidor de todos los ácidos. También se estudian parámetros termodinámicos como la energía de activación (Ea), la energía libre de adsorción (¿G°a), el calor de adsorción (Qads), la entalpía (¿H) y la entropía (¿S). La pendiente del tafel en presencia de inhibidores indica su efecto tanto en el proceso anódico como en el catódico durante la corrosión del zinc en el ácido nítrico.…

Taschenbuch. Condizione: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - La présente étude a été réalisée pour évaluer la perte par corrosion du zinc métallique dans différentes concentrations d'acide nitrique et pour la protection du zinc métallique. L'auteur a utilisé des amines aromatiques (Toludines, Nitroanilines, Chloroanilines) et des amines aliphatiques (Ethanolamines, Ethylamines). La perte par corrosion du zinc augmente avec l'augmentation de la concentration de tous les acides. La perte par corrosion est affectée par la présence d'oxygène de diffusion, la nature de la réaction complexe qui a lieu et également la nature du film protecteur. L'efficacité d'inhibition a été augmentée dans toutes les amines aromatiques étudiées à tous les inhibiteurs d'inhibiteurs avec augmentation de l'acide. Dans tous les types d'amines aromatiques o-chloro aniline, la m-nitroaniline s'est avérée être un excellent inhibiteur. Dans toutes les amines aliphatiques, l'éthanolamine s'est révélée être un excellent inhibiteur dans tous les acides. Les paramètres thermodynamiques tels que l'énergie d'activation (Ea), l'énergie libre d'adsorption (DeltaG°a), la chaleur d'adsorption (Qads), l'enthalpie (DeltaH) et l'entropie (DeltaS) sont également étudiés. La pente de Tafel en présence d'inhibiteurs indique leur effet sur les processus anodique et cathodique lors de la corrosion du zinc dans l'acide nitrique.…

Het corrosieverlies van zink neemt toe met toename van alle zuurconcentraties. Het corrosieverlies wordt beïnvloed door de aanwezigheid van diffusiezuurstof, de aard van de complexe reactie die plaatsvindt en ook de aard van de beschermende laag. Inhibitie Efficiëntie werd verhoogd in alle onderzochte aromatische amines bij alle remmers met toename van zuur. In alle soorten aromatische aminen o-chloro-aniline is m-nitroaniline een uitstekende remmer gebleken. In alle alifatische amines is ethanolamine bewezen een uitstekende remmer te zijn in alle zuren.
