In this study, it is aimed to develop hydrophobic microparticles as an alternative to existing methods and to determine the 17 beta-estradiol adsorption performance of this adsorbent to purify the 17 beta-estradiol hormone which is found as an endocrine disruptor in environmental waters with high capacity and low cost. In this study, L-phenylalanine containing Poly(HEMA-MAPA) microparticles were synthesized by microemulsion polymerization and used as adsorbent. Microparticles were characterized by Fourier transform infrared spectroscopy (FT-IR) and scanning electron microscope (SEM) methods. The size of the Poly(HEMA-MAPA) microparticles used was measured as 120-200 nm. Specific surface area and elemental analysis studies were also conducted. While the surface area of the particles was found to be a very high value of 1890 m(2)/g, the amount of incorporation of MAPA into the polymeric structure was calculated as 0.43 mmol/g. Adsorption studies were carried out in the batch system under different ambient conditions (17 beta-estradiol concentration, temperature, ionic intensity). The adsorption capacity of Poly(HEMA-MAPA) microparticles was calculated to be 98.4 mg/ g. Isotherm models for adsorption interaction were investigated deeply, and it was determined that the adsorption mechanism is suitable for Langmuir isotherm.eninfo:eu-repo/semantics/openAccessadsorptionestradiolhydrophobicL-phenylalaninemicroparticleArticle41322623410.1515/polyeng-2020-0150Q4WOS:0006263451000072-s2.0-85100996087Q3
