Determination of Nine Microelements in Nostoc commune Vauch by ICP-AES

Abstract:

In this paper,the contents of nine elements including Cu, Fe, Mn, Zn, Al, Cd, Pb, Ti and V were determined by ICP-AES technique, which elements originated from Nostoc commune Vauch from different places. Detection limits ranged 0.0018 ug•ml-1 and 0.068 ug•ml-1, the relative standard deviations for all these elements were lower than 2%, and recovery rates ranged 95.8% and 105.6%. The results showed that there were rich elements in N. commune Vauch from different places; contens of Fe, Al and V were highest; contents of Mn, Zn and Ti were moderately high,and contents of Cu, Cd and Pb were lowest. Futhermore, Cu, Fe, Mn, Zn and V were essential to people’s health,and Al, Cd, Pb and Ti had potentially physiologically toxic.Finally,Concentrations of elements within N. commune Vauch from different places were different,which may have some relations with the soil and environment where N. Commune grew.As a result, the determining method which elements of N. Commune are determined by ICP-AES is rapid,accurate and convenient, and wild N. Commune may contain toxic elements because of pollutional soil and environment,so N. Commun cultivated artificially can effectively reduce harmful elements.
