Manufacture of basic chromium sulphate and its impact on the environment

Abstract

In this study, basic chromium sulfate was prepared, and the product was manufactured from the widely used triple chromium, in addition to sodium chr omate and calcium chromate in certain proportions at a temperature of 1200 °C, as well as using sulfuric acid and glucose as shown in the experiment. Manufacturing until we get the final product. Some of the devices used in the mass production process, such as the CSTR reactor and dryer, were designed, with a brief explanation of the rest of the devices used. In addition, a study was conducted on the environmental impact of the product, in proportion to the industrial need and to achieve the slogan of clean and environmentally friendly work. Although there is no environmental impact of the product that has been manufactured, care must be taken when dealing with these materials as well as safety and health precautions must be used professional establishments. The sample was done and completed of the skin was taken and treated with the basic chromium sulfate that was manufactured, and some chemical tests were conducted on the sample, and the conclusion is that the base percentage is 33.33%, the percentage of chromium oxide is 3.8%, and the total ash percentage is 2.25%, and these percentages show the quality of the product.
