alumino-ferricadj.n.

Brit.

/əˌl(j)uːmᵻnəʊˈfɛrɪk/, U.S.

/əˌlumənəˈfɛrɪk/

Origin: Formed within English, by compounding; modelled on a French lexical item. Etymons: alumino- comb. form, ferric adj.

Etymology: < alumino- comb. form + ferric adj., after French alumino-ferrique (1833 or earlier).

Chemistry.

A. adj.

Containing both aluminium and iron; spec. designating the substance alumino-ferric (see branch B.); relating to this substance.

1874 W. Crookes Pract. Handbk. Dyeing 297 These particles..take up the alumino-ferric precipitates.

1883 Jrnl. Soc. Chem. Industry 2 45/1 Then alumino ferric cake, in quantity not too great to be decomposed by the lime salt present, is added.

1925 Brit. Med. Jrnl. 22 Aug. 349/1 To circulate the water..through a rough gauze strainer to arrest any large objects, and then to treat it with an alumino-ferric coagulant, so as to separate all the colouring matter.

1969 Libr. Q. 39 177 Other additives, such as iron-free alum, aluminoferric alum, iron oxide, sequestering..agents, and titanium dioxide, had little, if any, effect.

2005 A. N. Shilton Pond Treatm. Technol. 94 Natural compounds containing alumino-ferric compounds..can be added.

B. n.

An impure form of aluminium sulphate containing ferric oxide, used esp. as a coagulating and flocculating agent for water purification, sewage treatment, etc.

1878 Lancet 26 Oct. 606/1 The fine silicous matter..contained in the alumino-ferric is found to assist rather than retard the precipitation.

1908 Chambers's Jrnl. May 295/2 The alumina compound most generally used..is that known as aluminoferric.

1948 Sewage Wks. Jrnl. 20 588/1 Samples of spent emulsified cutting oils were treated with varying proportions of solutions of aluminum sulfate, aluminoferric, ferric chloride, [etc.].
