Model Kesetimbangan Pada Adsorpsi Ion Kadmium Menggunakan Hidroksiapatit Dari Kulit Kerang Darah

Abstract: Pencemaran logam berat kadmium (Cd2+) di perairan mengakibatkan kerusakan yang besar bagi kehidupan manusia. Salah satu cara untuk menghilangkan dan mengurangi logam cadmium adalah menggunakan proses adsorpsi. Larutan kadmium (Cd2+) 3mg/L sebanyak 200 mL ditambahkan HAp 0,5 gr dan diaduk dengan kecepatan 100, 200 dan 300 rpm pada suhu 30°C, 40°C dan 50°C. Larutan kemudian dianalisa menggunakan Atomic Adsorption Spectroscopy (AAS) untuk mengetahui konsentrasi kadmium. Semakin besar suhu adsorpsi maka kapasitas … Show more

“…In this research, the KF dan 1⁄n value obtained was 30.3599 mg.g -1 and -1.414, respectively. Because the value of 1/n is less than 1, this indicates that the chemical adsorption process is running [37]. Research by Hasrianti (2015) [12] carried out Cd 2+ adsorption using cassava peel biosorbent following Freundlich isotherm model.…”
