The materials were characterized by FTIR spectroscopy, scanning electron microscopy (SEM)-EDS studies. Characterization by FTIR showed that the IIPs have been successfully synthesized as indicated by the absence of a peak for the alkene functional group at 3000–3300 cm–1. From the FTIR data and SEM-EDS images showed that Y(III) ions have been successfully released from the polymer. The retention properties by batch procedure showed that the adsorption capacity of Y(III)-IIPs was 10.26 mg/g at pH 7 with a contact time of 10 min. Y(III) ions adsorption onto Y(III)-IIPs follows the Langmuir adsorption isotherm with a correlation coefficient of 0.9671, which showed a maximum adsorption capacity value of 14.68 mg/g and follows the Lagergren pseudo-second order kinetics model. The IIPs materials selectivity against other rare earth metals showed a better selectivity than NIPs.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Adsorption capacities,Correlation coefficient,Imprinted polymers,Ion imprinted polymer,Langmuir adsorption isotherms,Non-imprinted polymers,Pseudo second order,Pseudo second order kinetics[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]adsorption,imprinted polymers,Langmuir adsorption isotherm,pseudo-second order,rare earth elements,yttrium[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]We would like to express our gratitude to the Insti-tut Teknologi Bandung for their financial support through Riset Insinas 2017.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.3103/S1067821217060189[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
