Abstract This experiment is the use nonwoven the bottom layer as chitosan nonwoven , and uses chitosan to soak the prepare the adsorption medium. To differ weave and different prepareation method on the adsorption test analysis. The experiment first aims at nonwoven to carry on chitosan to adhere to stick cohere the test.PP and PETnonwoven immersion in 5% acetic acid one night, again immersion in the 1%(w/w) chitosan solution a night. Then carries on the immersion by different concentration 1~3M NaOH, finally carries on its nonwoven dries in the shade finally carries on its nonwoven dries in the shade. Will have adhered to stick chitosan nonwoven to investigate its adsorptions of heavy metal ions Cu+2, Pb+2,Zn+2,Mn+2,Cr+3,Ni+2,Cd+2.By atomic absorption spectroscope (AA) analysis. The adsorption analysis result understood that chitosan nonwoven adsorbs the heavy metal effect.
