the ultrasound assisted emulsification microextraction (usaeme) method followed byinductively coupled plasma-atomic emission spectrometry (icp-aes) was used for preconcentration anddetermination of bismuth (bi), indium (in) and lead (pb) in the plant azolla filiculoides lam. calix [4] pyrrole was used as a chelating agent and tetrachloroethylene was selected as extraction solvent. the main para...

Changes in growth and ultrastructure of Azolla caroliniana in response to elevated UV-B radiation were investigated. Exposure of plants to UV-B radiation for 1, 8, 16, 24 and 48 h exhibited a significant decrease in biomass and relative growth rate. This decrease resulted in an increase in doubling time over the control. Also, Chl a and b contents were significantly decreased especially after 1...

biosorption of acidic dyes using the live fern azolla filliculoides was studied in a discontinuous system. dye parameters, dye initial concentration and contact time were studied in temperature range of 25-30 ?c and ph=7. it was shown that increasing the 23initial concentration of dye and its contact time resulted in decreasing the dye taking quantity by the absorbent. also, type of dye has an ...
