Potassium aluminium sulfate (Alum) A1K(S04)2.12H20 The aqueous immunogen solution/suspension is mixed with 0.3 vol 10% alum. The pH is then ac usted to about 8.0 with sodium hydroxide solution and the resultant precipitate washed in 0.9% NaCl solution and administered. Acetone precipitates The aqueous immunogen is precipitated with 4.5 vol of acetone at -20°C for 1 h. The precipitate is collected by centrifugation at lO.OOOg at room temperature, washed in 80% acetone, and air-dried. The pellet is resuspended in saline using a Dounce homogenizer and then administered directly or in association with... 

Merrifield (1849) describes how alumine zuccarino was alum (potassium/aluminium sulfates) groimd and heated with rose water, sugar and white of egg and allowed to harden by cooling. It was used as a base for lake pigments and in the preparation of verdigris qq.v.). 

According to Kiilm and Curran (1986), during the nineteenth century Baltimore chrome yellow was likely to have contained calcium sulfate and lead sulfate (qq.v.), or, according to Mierzinski (1881), alum (hydrous potassium aluminium sulfate, KA1[S04]2.12H20). They state that the term is now applied to a pale chrome yellow precipitated on gypsum or asbestine (q.v.). 

Kiihn and Curran (1986), citing Mierzinski (1881), indicate that old forms of this pigment consisted of chrome yellow (. v.) and alum, a hydrous potassium aluminium sulfate. The same pigment mixture is also given for Spooner s chrome yellow and Baltimore chrome yellow q.v.) by the same source. 

Heaton and Hurst do not appear to say the same thing, though Heaton is a revision of the text by Hurst. Bristow (1996b) states that Hurst says it is made from calcium sulfate and aluminium sulfate, adding that he thinks that it was made with alum (potassium aluminium sulfate) as opposed to aluminium sulfate.

Various workers [28,34,41] have used different extraction solutions in the ion-selective electrode method, depending on the soil being analysed. The most important are [28,32,35-37] potassium sulfate [39], aluminium sulfate [30], copper (II) sulfate [32], calcium hydroxide [33], and copper sulfate(II) with aluminium and silver resins [41 ]. 

Aluminum was named for one its most important compounds, alum. Alum is a compound of potassium, aluminum, sulfur, and oxygen. Its chemical name is potassium aluminum sulfate, KA1(S04)2- In North America, aluminum is spelled with one i and is pronounced uh-LOO-min-um. Elsewhere in the world, a second i is added— making it aluminium—and the word is pronounced al-yoo-MIN-ee-um.

The first significant step forward was the discovery that water is cooled when salts are dissolved in it, such as common salt (sodium chloride), saltpetre (potassium nitrate), sal-ammoniac (ammonium chloride) or alum (a mixture of aluminium sulfate and potassium sulfate). When the crystals dissolve, the strong bonds between the ions are broken, extracting heat from the surrounding water, so the temperature drops. Adding a mixture of 5 parts ammonium chloride and 5 parts potassium nitrate to 16 parts water at 10 °C causes the temperature of the mixture to drop to about — 12°C, sufficient to freeze a vessel of pure water immersed in it. This phenomenon was first recorded in an Indian poem from the fourth century AD, and described in detail in an Arabic medical textbook from 1242. Another book in Arabic, containing sorbet recipes, appeared at about the same time. 

Common Related Aluminium Compounds Aluminum occurs in nature as alum (potassium aluminum sulfate) which is used largely as a fixing agent for dyeing, and by doctors to stop bleeding, as well as a preservative in paper industry. 

Calcium sulfate and aluminium sulfate are used as fillers and glazes in the manufacture of papers. To detect these compounds in paper several eg. of the sample are ashed and the residue is then treated with several drops of a solution of potassium permanganate to which some barium has been added. For details see page 431 where the use of the Wohlers effect for the detection of sulfate is described. A positive response by the paper ash indicates the presence of sulfate but this test does not diflerentiate between these sulfates. See page 543 for the detection of calcium sulfate in paper.

Abundant yellow or white salt crusts are present on waste rock and at the surface of the soil. The crusts comprise alum-like sulfate minerals containing variable amounts of sodium, potassium, iron and aluminium, such as the mineral jarosite. They are often very soluble in water, releasing acid and precipitating ferric hydroxides. 

The original synthesis of diethyl teUnride by Wohler was carried out by treating potassium telluride with ethyl sulfate. The preparation of potassium telluride was rather inconvenient and involved the reduction of elemental tellurium by heating the element at red heat with potassium-hydrogen D-tartrate. An early report of Natta demonstrated that the treatment of aluminium telluride by alcohols or ethers at 250-300 °C is also a promising route to diorganyl tellurides.
