Effect of extraction times on determination of minerals in multivitamin tablets by ICP-OES / Normarziana Azman

In this study, 2 types of tomatoes and brinjals that were cherry tomato, beefsteak tomato, long brinjal and oval brinjal were chosen as samples. This study was carried out with the aim to assess the levels of arsenic (As), cadmium (Cd), copper (Cu), manganese (Mn), lead (Pb) and zinc (Zn) concentrat...
