摘要：
The adsorption of 2-phosphonobutane-1,2,4-tricarboxylic acid (PBTCA) and citric acid on alumina was determined by using the ferric 5-nitrosalicylate spectroscopic method. The saturation adsorption of PBTCA was found to be much higher than that of citric acid. FTIR and AES results revealed that the phosphonyl group participated in the chemisorption of PBTCA onto alumina. The higher dispersing efficiency of PBTCA than citric acid was attributed to its high number of charges and high chelating ability at high pH.
