THE RELATIONSHIP BETWEEN UNIVERSITY REPUTATION, BRAND PERSONALITY, BRAND ATTACHMENT AND STUDENT LOYALTY IN HO CHI MINH CITY

Abstract

The use of chelates to increase the accumulation of heavy metals in plant tissues is of great interest for method phytoremediation. In this study, the plant – growth experiments were carried out on a small scale in the laboratory. Spinacia oleracea were grown in soil pots contaminated with differrent concentrations of lead (0,140, 200, 400, 600 and 800 mg/kg soil) and 3 gram of chelates such as Trlion B, acid citric, acid succinic for 10 days. Our results showed that, Spinacia oleracea still were grown well in 600, 800 mg/kg concentrations of  lead. In addition, the reults of atomic adsorption spectroscopy (AAS) demonstrated that, the addition of chelates (Trilon B, citric acid, succinic acid) to a Pb contaminated soil were a lot increased accumulation of Spinacia oleracea.
