Aplikace arašidového odpadu k odstranění železa z vodné matrice

Abstract

The aim of this Master´s thesis focuses on the removal of heavy metal contamination from peanut skin extracts by waste biomass adsorption. The essence of the Master´s thesis is the search of ideal conditions for the removal of iron also describe the sorption studies and evaluation results which they can help to further research and improve the conditions for the removal of metal. The theoretical part is focused on the state of the topic of sorption also description and characteristics of the technology used and the selected sorbent. The experimental part describes the preparation of the sorbent and the evaluation of measured values and modeling mathematical models. The grain fractions was used < 0,5 – 1,0 mm activated in sodim hydroxide at a concetration 0,1 mol/l with exposure time 20 minutes. By study it was found that the efficacy was 84% with adsorption capacity q = 10,65 mg/l the optimal pH value was chosen pH = 6,0. At the comparison the Langmuir model with adsorption coefficient appeared better with value r = 0,9902. Everything analyzes were perfomes at a laboratory temperature of 21 ° C at 150 rpm.
