Figure 8

Relative fluorescence intensity of DA/SBA-15 (1 × 10−5 M) in the presence of various interfering ions (0.15 mM, black bars) and coexistence (red bars) of interfering ions (0.15 mM) with Hg2+ (0.15 mM), in 15% ethanol/water solution (λex = 335 nm). Interfering ions containing 1 no ions, 2 Hg2+, 3 Zn2+, 4 Cd2+, 5 Fe2+, 6 Co2+, 7 Ni2+, 8 Pb2+, 9 Cu2+, 10 Ag+, 11 Mn2+, 12 K+, 13 Ca2+, 14 Na+, 15 Mg2+, 16 Ba2+, 17 Al3+
