The mussels’ reference materials were analyzed by inductively coupled plasma spectrometry and mass spectrometry, K, Na, Ca, Mg, P, Al, Fe, Zn, Nn and Sr were determined by spectrophotometry, Cr, Cu, Ca, Ce, Mn, Mo, Ni, Pb, Se, Sr, U and V. Under the optimized working conditions, the effects of polyatomic ions (39) K ~ (16) O, ~ (39) K_2, ~ (40) Ar ~ (16) O, ~ (42) Ca ~ (16) O, ~ (44) Ca ~ (16) O, ~ 31 P ~ (40) Ar ~ (37) Cl, ~ (35) Cl ~ (16) O, ~ (37) Cl ~ (16) O and ~ (40) Ar ~ (12) Se, ~ (63) Cu, ~ (59) Co, ~ (58) Ni, ~ 60 Ni, ~ 75 As, 77 Se, ~ 51 V, ~ 53 ) Cr and ~ (52) Cr, as well as the digestion methods of HNO_3 + H_2O_2 (3 + 2), HNO_3 + HClO_4 (3 + 0.5) and HNO_3 + H_2SO_4 (3 + 0.5) Apparent concentration at the isotope. The detection limit of spectrometry is 0.001 ~ 0.75mg / L, and the detection limit of mass spectrometry is 0.005 ~ 1.01μg / L. The relative standard deviations of spectrometry and mass spectrometry were 2.7% ~ 12.8% and 3.4% ~ 24.8%, respectively.
