Membran kitosan termodifikasi poli etilen glikol (peg) dan polidopamin (pda) telah dibuat dengan metoda pelapisan (coating). Terdapat perbedaan fisik dari membran sebelum dan sesudah modifikasi. Kapasitas adsorpsi membran kitosan sebelum dan sesudah modifikasi telah dianalisis dengan menggunakan larutan yang mengandung ion Pb(II) sebagai target polutan. Kapasitas adsorpsi tertinggi diperoleh oleh membrane kitosan termodifikasi 10% peg dan pda sebanyak 1 kg/L dengan besar %R yaitu 54%.
