Sodium Silicate is a chemical compound that has properties such as water glass is a colorless, soluble in water, and is widely used in industry. Therefore, the extraction of sodium silicate by alkaline fusion is followed by water leaching. The alkaline fusion process is a technique that is often used and can further simplify the extraction process. The purpose of this research in general is to obtain the optimum conditions for the extraction of sodium silicate from the Sidoarjo mud in an alkaline fusion process followed by water leaching. The alkali used in the alkaline fusion process is NaCO. The effect of various experimental conditions on fusion has been studied. These variables include the amount of alkali used, the reaction temperature, and the length of the reaction time. The alkaline fusion process proved that sodium silicate could be produced and could be separated in water leaching. The highest percentage of sodium silicate extraction was 43.6% resulting from water leaching conditions with a solid-liquid ratio of 1:5, a temperature of 80 °C for 2 h.
硅酸钠是一种化合物，具有水玻璃的性质，无色、可溶于水，在工业中广泛使用。因此，通过碱熔提取硅酸钠后进行水浸。碱熔过程是一种常用技术，可进一步简化提取过程。本研究的总体目的是获得在碱熔后水浸的过程中从西多阿乔泥中提取硅酸钠的最佳条件。碱熔过程中使用的碱是NaCO。研究了各种实验条件对熔合的影响。这些变量包括碱的用量、反应温度和反应时间长度。碱熔过程证明可以生产硅酸钠并在水浸中分离出来。硅酸钠提取的最高百分比为43.6%，这是在固液比为1:5、温度为80°C、时间为2小时的水浸条件下得到的。
