| 摘要 |
<p>The subject of the present invention is aluminium polychlorosulphates having improved properties, their process of preparation and application of these aluminium polychlorosulphates to the treatment of drinking water, of aqueous effluents and in the papermaking industry. The aluminium polychlorosulphate has the formula: Al(OH)aClb(SO4)cMdNe in which: M represents an alkaline-earth metal; N represents an alkali metal; a, b, c, d and e are numbers such that: 1.95<a<2.4, 0<c<0.15, 0<d<0.16, 0<e<1.7, a + b + 2c = 3 + 2d + e.</p> |
