A method of microwave digestion axial-view ICP-AES was applied to determine heave metals trace elements lead,arseic,cadmium in honey products. Operation parameters of ICP-AES and condition were optimized and selected. The detection limit was Pb:2.9×103 mg/L,As:5.2×103 mg/L,Cd:0.056×103 mg/L.The RSD was in the range of 2.9 %-8.5 % and the recovery was in the range of 91 %~102 %.This method was compared with the national standard way and their resultes showed no significant difference from that of the national standard way .The resulte was satisfactory for honey products.
