4 Potash alum is a potassium aluminum sulfate dodecahydrate It is a white crystalline solid that is soluble in water It is used in the manufacture of paper dyes and fireworks The first step in the preparation of potash alum is the preparation of aluminum sulfate Aluminum sulfate is made by reacting aluminum metal with sulfuric acid
The anhydrous form occurs naturally as a rare mineral millosevichite found for example in volcanic environments and on burning coal mining waste sulfate is rarely if ever encountered as the anhydrous salt It forms a number of different hydrates of which the hexadecahydrate Al 2 SO 4 3 ·16H 2 O and octadecahydrate Al 2 SO 4 3 ·18H 2 O are the
Response Surface Methodology aluminum sulfate 1 Introduction For a very long time aluminum sulfate is a well known coagulant being used in water and wastewater treatment as a preferred reagent Usage of aluminum sulfate is based on several advantages as low cost high efficiency at low doses low toxicity and high availability [1]
Aluminum sulfate could drastically decrease the setting time from more than 200 min to only a few minutes as shown in Fig 10 [13] When aluminum sulfate dosage was higher than 6% the decreasing rate became gentle which means that 6% may be the optimal dosage of aluminum sulfate Similar result was obtained by Chen and Sun [69]
In a clean 250ml beaker of potassium sulphate crystals were transferred and 20ml of water was added and stirred till crystals get dissolved Then another beaker was taken and 10g of aluminium sulphate crystals were transferred to which 20ml of water and 1ml of dilute H 2 SO 4 was added to prevent hydrolysis of aluminium sulphate
