Abstract

Adsorpsi Zn (II) daril arutan berair menggunakan kulit pisang (Musa paradisiaca) sebagai biosorben telah dikaji dengan menggunakan metode kolom. Proses adsorpsi dikaji terhadap beberapa parameter,seperti pH, konsentrasil arutan Zn (II) mula-mula, massa biosorben, ukuran partikel biosorben dan laju alir. Kondisi optimum proses adsorpsi Zn (II) dengan biosorben kulit pisang berlangsung pada pH 3 dengan konsentrasi larutan Zn (II) mula-mula 500 mg/L, massa biosorben 0,6 g, ukuran partikel biosorben 250 µm dan laju alir 2 mL/min memiliki kapasita sadsorpsi 7,8567 mg/g. Berdasarkan hasil penelitian dapat disimpulkan bahwa kulit pisang, sebagai limbah, memiliki potensi yang baik sebagai biosorben untuk menyerap logam berat, seperti seng (Zn) dari perairan.   The removal of Zn (II) from aqueous solutions using banana (Musa paradisiaca) shell as biosorbent has been studied with column method. The parameters of adsorption such as pH, initial concentration, biosorbent dose, particle size and flow rate were investigated. The optimum condition was at pH=3, concentration 500 mg/l, biosorbent dose 0,6 g, 250 μm particle size and 2 ml/min flow rate with adsorption capacity 7,8567 mg/g. This study concluded that banana shell, a waste material, have good potential as biosorbent to remove toxic metals like zink from water.
腌制Zn (II) daril arl水处理香蕉皮(摩西范例)是用柱式方法进行的。培养过程是对一些参数进行研究的,比如pH, ar那Zn (II)的浓度,首先是生物降解质量,生物降解粒子的大小和流速。最佳条件蛋白酶Zn (II)过程与biosorben香蕉皮于pH值3锌溶液的浓度(II)首先500 mg / L,质量biosorben 0.6 g, biosorben 250µm颗粒的大小和2 mL / min流量有kapasita sadsorpsi 7.8567 mg / g。研究表明,香蕉皮作为废物,具有从水中吸收锌(Zn)等重金属的良好潜力。Zn (II)从水溶液之除用香蕉(摩西paradisiaca)美国壳牌公司biosorbent解决方案已经和纵队studied方法。pH adsorption parameters》这样的美国,最初双臀biosorbent剂量,粒子大小和流动速率是investigated。《最佳condition was at pH = 3,双臀500 mg / l, biosorbent剂量0.6 g, 250μm的粒子大小和2 ml / min流率和adsorption capacity 7.8567 mg / g。这个研究结论那香蕉壳牌公司a浪费材料,有祝美国潜在的biosorbent要移除metals像锌从水有毒。
