Modified zeolite as a means of purifying irrigation water – Study
PhD Thesis – Author: Dionysiou, Ourania-Nina S., Supervisor: Misopolinos, Nikolaos, Aristotle University of Thessaloniki, School of Agriculture, 2010. This study investigated certain conditions that influence the adsorption of B and P on surface-modified natural zeolite (clinoptilolite), with hexadecyl-trimethyl-ammonium bromide (C19H42BrN or HDTMA–Br), with a view to its use as a decontamination agent for irrigation water and aquatic systems. Specifically, the following were investigated: (a) the effect of washing the zeolite with HCl prior to its modification, and (b) the effect of increasing the pH on the adsorption of B by the zeolite. Subsequently, the following were investigated: c) the effect ... Read more
