Bu calismada, Direct Blue 2 (DB2) diazo-boyar maddesinin poli(Hidroksietil metakrilat) [P(HEMA)] nanopartikulleri ile sulu cozeltiden giderimi calisilmistir.  Adsorpsiyona ortam pH’inin, sicakligin, baslangic boya derisiminin ve temas suresinin etkileri incelenmistir.  Optimum kosullar altinda, 50 mg/mL baslangic boya derisimi ve 2 mg polimer kullanilarak % 89.1 giderim elde edilmistir.  Adsorpsiyon mekanizmasinin anlasilabilmesi icin Langmuir, Freundlich ve Sips (Langmuir-Freundlich) izoterm sabitleri hesaplanmistir.  Elde edilen verilere gore adsorpsiyonun Langmuir izoterm modeline uygun oldugu (R2: 0.993, Qmax: 27.1 mg/g) rapor edilmistir.  Adsorpsiyon oncesi ve sonrasi boya derisimleri UV-Vis spektrofotometresinde olculmus, adsorpsiyon oncesi ve sonrasi polimer FTIR ve SEM ile karakterize edilmistir.
