| Abstract: | Objective:The inductively coupled plasma atomic emission spectrometry(ICP-AES)method for determining of eight elements in organic fertilizer were established,in order to provide technical supported for scientific investigation of nutrient elements in organic fertilizer.Method:The samples were digested by Electric heating board digestion method.The contents of nutrient elements including Mn,Fe,Zn,Cu,Ca,Mg,K,P in the organic fertilizer samples were determined by ICP-AES.Result:The detection limits 0f eight nutrient elements were 0.1~13.7mg/kg,and the relative standard deviation(RSD)Was 0.9%~2.7%.Recovery was in the range of 88.5%~115%.Conclusion:detennination of nutrient elements in organic fertilizer by ICP-AES has advantages of easy operation,good selectivity,high sensitivity and accuracy.It can be application and dissemination in nutritive value assessment of organic fertilizer. |
