Abstract
กรรมวิธีเพื่อการเก็บรวบรวมในเวลาเดียวกัน และการตกตะกอนของปรอท ในแก๊สที่มันประกอบอยู่ จะประกอบขึ้นด้วยการผ่านแก๊สปรอทนี้ ไปยังหอสูง เพื่อการล้าง ที่ซึ่ง ไฮโดรเจนซัลเฟอร์ (แก๊ส) ถูกฉีดเข้าไปอย่างต่อเนื่องและฉีดเข้าเป็นช่วง ๆ ด้วยเวลาที่ เท่ากับ ซึ่งจะต้องมีสารละลายน้ำที่ประกอบอยู่ด้วย สารประกอบเชิงซ้อน ปรอท (II) ที่ เสถียรในสภาพกึ่งกรด เช่น [I2Hg] 2- หรือ [(SCN)4Hg] 2- โดยไม่ ต้องการสารออกซิแดนท์ที่เติมเข้าไป โดยทั้งคู่ของการเก็บรวบรวมและการตกตะกอน ของปรอทและการสร้างขึ้นมาใหม่ของสารละลายจะมีสารประกอบเชิงซ้อนปรอท (II) ประ กอบอยู่ด้วยในเวลาเดียวกัน ในขั้นตอนเดียว Process for simultaneous collection And the precipitation of mercury In the gas it contains It consists of passing this mercury gas into a high tower for purification, where hydrogen sulfur (gas) is continuously injected and injected at intervals equal to which an aqueous solution is required. Semi-acid stable mercury (II) complexes such as [I2Hg] 2- or [(SCN) 4Hg] 2- without the need for added oxidants. By both the collection and the precipitation Of mercury and the reconstruction of the solution will contain the mercury (II) complex at the same time. In one step
