Taninski flokulanti

Tišler, Vesna (author), Golob, Gabrijela (author), Rutar, Vera (author)

Sintetizirali smo flokulante iz različnih vrst tanina. Za sintezo smo uporabili tanin smreke, smreke-jelke, hrasta, mimoze, alepskega bora in kvebrača ter ustrezne kemikalije. Osnova za pridobivanje kationskih flokulantov je bila Mannichova reakcija, ki smo jo izvajali v digestoriju ob stalnem mešanju pri konstantni temperaturi. Testiranje flokulantov je potekalo na standardizirani napravi floktester. Zeta potenciale smo izmerili na zetametru Laser zeetm 501.

Abstract

Various kinds of tannin flocculants were synthesised using spruce tannin, spruce-fir tannin, oak tannin, mimosa tannin, aleppo pine tannin, quebracho tannin, with suitable chemicals. Cationic flocculants were obtained on the basis of the Mannich reaction performed at constant mixing and constant temperature. The testing of flocculants was performed by standardised flock tester. Zeta potentials were measured using Laser Zeetm 501 zeta meter.
