氧化铝浸出从三个地方ukpor粘土,auchi和udi来自尼日利亚的不同位置进行了使用三种不同的酸(盐酸,硫酸和硝酸)作为沉淀剂。粘土的浸出过程制备样品,溶解在酸溶液中,降水基本硫酸铝的滤液和EDTA滴定法的使用得到氧化铝产量。工艺参数的影响(酸浓度、粒度、浸出温度和酸泥重量比)对氧化铝提取研究。阶乘设计实验技术是用于评估实验因素对最终结果的影响。粘土特性也进行了不同的粘土样品。最高产量的36.96%是来自auchi粘土与硝酸收益率比盐酸和H2 SO4氧化铝。氧化铝是重要的工业矿物,可以用作催化剂、磨料和吸附剂。氧化铝(α-alumina)存在于稳定形式。氧化铝是自然纯粹的形式的矿物刚玉,虽然最重要的天然矿物质铝土矿氧化铝。铝土矿已经广泛应用于工业通过拜耳法生产氧化铝。 No occurrence of bauxite has been reported in Jordan. One of the alternative sources, however, is Al-rich kaolin, which is a hydrated aluminum silicate (Al2Si2O5 (OH) 4) made of mineral kaolinite. Hydrochloric acid is a colorless inorganic chemical system. HCl is the formula of it. Muriatic acid is another name of it. As it dissociates completely in an aqueous solution, it can attack the skin over a wide range of composition. It is a solution of hydrogen chloride and water, as well as a variety of other chemical species, including hydronium and chloride ions. It is a natural component of stomach acid produced in the digestive systems of most animal species, including humans. Hydrochloric acid is an important chemical reagent and an industrial chemical, used in the production of polyvinyl chloride for plastic. In households, dilute hydrochloric acid is often used as a descaling agent. Hydrochloric acid is also used in the treatment of leather. Sulfuric acid is a mineral acid. It is composed of sulfur, oxygen and hydrogen elements. Vitriol oil is another name of it. H2SO4 is the molecular formula of it. It is a colorless, odorless and viscous liquid, soluble in water and synthesized in highly exothermic reactions. Its corrosivity can be mainly attributed to its strongly acidic nature and, if at a high concentration, to its dehydrating and oxidizing properties. It is also hygroscopic, easily absorbing water vapor from the air. On contact, sulfuric acid can cause severe chemical burns and even secondary thermal burns; it is very dangerous even at lower concentrations. Sulfuric acid is a very important chemical, and domestic production of sulfuric acid is a good indicator of its industrial strength. It is widely produced with different methods, such as the contact process, the wet sulfuric acid process, the lead chamber process and some other methods. It is most often used in the manufacture of fertilizers, but it is also important in mineral processing, petroleum refining, wastewater treatment and chemical synthesis. It has a wide range of end applications, including in household acid drain cleaners, as an electrolyte in lead batteries, in the dehydration of a compound, and in various cleaning agents. Nitric acid is a highly corrosive mineral acid. HNO3 is the molecular formula of it. Acuq fortis and spirit of niter are another names of it. When the solution contains more than 86% HNO3, it is called fuming nitric acid. Fuming nitric acid is further characterized as red fuming nitric acid at concentrations above 86%, or white fuming nitric acid at concentrations above 95% based on the amount of nitrogen dioxide present. Nitric acid is the main reagent used for nitration - the addition of a nitro group, usually to an organic molecule. While some resulting nitro compounds are explosives sensitive to shock and heat, some are stable enough to be used in ammunition and demolition, while others are even more stable and used as pigments in inks and dyes. Commonly, it is also utilized as a strong oxidizing agent.
