Abstract：Metal elements, especially the heavy metal element, need to be considered for resource utilization of paper sludge.Seventeen kinds of metal elements were determined by ICP-AES method, which were form two kinds of paper sludge from Anhui Shanying paper mill, one kind of paper sludge from Fujian Qingshan paper mill, and one kind of paper sludge from Fujian Zhongzhu paper mill.The results show that there are different amounts of metal elements in the 4 kinds of paper sludge including poisonous metal elements, such as Cr, etc, metal element which is poisonous when excessive, such as Fe, etc, and P and K which are beneficial for plant growth.Al and Ca contents are maximal.The recovery ratio for Fujian Zhongzhu paper mill obtained by standard addition method is 94.4%-107.3%.Heavy metal elements content lower than the national standard GB/4284—84 “Control standards for pollutions in sludge form agricultural use”.The order of heavy metal elements content is paper sludge from Fujian Zhongzhu paper mill＜paper sludge from Fujian Qingshan paper mill＜paper sludge from Anhui Shanying paper mill.The results provide theoretical directions for resource utilization of paper sludge, especially for agricultural utilization and land utilization.
Key words：Paper sludge;ICP-AES method;Metal element;Heavy metal element;Resource utilization
