Abstract

Sposób otrzymywania adsorbentu do usuwania metali ciężkich charakteryzuje się tym, że mieszankę, co najmniej skrobi stanowiącej od 50% wagowych mieszanki i polisacharydów nieskrobiowych, nawilgaca się do zawartości wody od 15 do 30%, kondycjonuje się do 24 godzin. Następnie poddaje procesowi ekstruzji przy obrotach podajnika od 30 do 200 obr/min., stopniu sprężenia ślimaka od 2:1 do 4:1; obrotach ślimaka 80 do 160 obr/min., obrotach noża granulatora od 80 do 400 obr/min., średnicy dyszy w zakresie od 2 do 5 mm, w temperaturze pierwszej strefy ekstrudera od 40 do 80°C, środkowej strefy ekstrudera od 45 do 100°C oraz końcowej strefy od 55 do 140°C, po czym, natychmiast po opuszczeniu ekstrudera, materiał umieszcza się w wodzie destylowanej i/lub roztworach soli i/lub oleju, i/lub rozpuszczalniku organicznym i pozostawia na czas do 72 godzin. Następnie oddziela się nadmiar cieczy i tak otrzymany, gotowy produkt, konfekcjonuje się.The method of obtaining an adsorbent for removing heavy metals is characterized in that a mixture of at least starch constituting from 50% by weight of the mixture and non-starch polysaccharides is moistened to a water content of 15 to 30%, and is conditioned for 24 hours. Then it is subjected to the extrusion process at the feeder speed from 30 to 200 rpm, the screw compression ratio from 2:1 to 4:1; screw speed from 80 to 160 rpm, granulator knife speed from 80 to 400 rpm, nozzle diameter from 2 to 5 mm, temperature of the first extruder zone from 40 to 80°C, middle extruder zone from 45 to 80°C 100°C and the final zone from 55 to 140°C, then, immediately after leaving the extruder, the material is placed in distilled water and/or salt solutions and/or oil and/or organic solvent and left for up to 72 hours. Then, excess liquid is separated and the finished product thus obtained is packaged.
