| Judul Artikel | SINTESIS BEADS CROSSLINK KITOSAN TRIPOLIFOSFAT DAN APLIKASINYA DALAM MENURUNKAN KADAR Ni(II) PADA AIR LINDI |
| Abstrak | Telah dilakukan sintesis crosslink kitosan-tripolifosfat dan aplikasinya dalam penurunan kadar nikel pada air lindi. Sintesis crosslink kitosan tripolifosfat dilakukan dengan mereaksikan larutan kitosan dengan natrium tripolifosfat pH 3. Kitosan dan crosslink kitosan tripolifosfat dikarakterisasi dengan spektroskopi FTIR dan penentuan kaadar fosfor. Studi adsorpsi nikel pada air lindi menggunakan crosslink kitosan tripolifosfat dilakukan pada variasi waktu kontak dan perbandingan adsorben dan adsorbat. Variasi perbandingan adsorben dan adsorbat pada larutan Ni(II) digunakan untuk kajian adsorpsi isotermal. Crosslink kitosan tripolifosfat dapat meurunkan Ni(II) pada air lindi dan mengikuti pola adsorpsi isotermal Freundlich. |
| Abstrak (Inggris) | Synthesis of chitosan-tripolyphosfate crosslink had been done and its application for nickel adsorption in leachate. The synthesis of chitosan-tripolyphosfate crosslink in this research was carried out by reacting a solution of chitosan in acetic acid with sodium tripolyphosfate pH 3. The chitosan and chitosantripolyphosfate crosslink were characterized by FTIR and determination of phosphorus. Chitosan-tripolyphosfate was used to adsorp nickel with parameters the influence of contact time variation and the ratio of adsorbent and adsorbate. Variation of the ratio of adsorbent and adsorbate is used to study the adsorption isotherm. Crosslink chitosan tripolyphosphate can adsorb nickel in leachate and following Freundlich adsorption isotherm pattern. |
