BIDIMENSIONAL POROUS MATERIAL, PROCESS OF PRODUCTION OF BIDIMENSIONAL POROUS MATERIAL, PROCESS OF DISCOLOR

NOVELTY – The porous, bi dimensional, hydroxide, double laminar material is constituted by magnesium and aluminum metallic cations and nitrate as anion in the ratio Mg2:+Al3+ equal for two for decoloration of textile effluents containing anionic colorants in its original pH and reduction of the concentration of inorganic anions present in such effluents. USE – For the decoloration of textile effluents containing anionic colorants. ADVANTAGE – The efficiency of decoloration in the recycling is above 92 per cent and there are no significant alterations in the absorption properties, it being possible to use the initial material at least five times. DETAILED DESCRIPTION – The colorants and inorganic anions are decomposed thermally, followed by the addition of the product of decomposition to a new sample of the effluent.

Main Application Field

D15 (Chemical or biological treatment of water, industrial waste and sewage – including purification, sterilising or testing water, scale prevention, treatment of sewage sludge, regeneration of active carbon which has been used for water treatment and impregnating water with gas e.g. CO2, but excluding plant and anti-pollution devices (C02).); F06 (Chemical-type treatment of textiles (D06B, L, M, P, Q).)
