Abstract

Pada penelitian ini telah dibuat adsorben komposit serbuk cangkang kupang-khitosan yang terikat silang glutaraldehid 0,2% dimana masing-masing bahan dapat mengikat iogam Cu (II) secara kontinu menggunakan sistem fixed-bed kolom.. Adsorben cangkang kupang-khitosan ini dimasukkan ke dalam kolom yang berdiameter 1,5 cm dan konsentrasi awal larutan Cu (II) adaiah 100 mg/L. Variasi yang digunakan adaiah laju alir influen (1,5 mL/menit; 2 mL/menit; dan 2,5 mL/menit), variasi komposisi adsorben dibuat daiam fraksi berat serbuk cangkang kupang (93,75%; 95,24%; dan 96,15%), dan juga variasi pH awal larutan (dengan pengaturan dan taspa pengaturan). Pada pH awal larutan yang tanpa pengaturan digunakan khusus untuk komposisi adsorben dengan fraksi berat serbuk cangkang kupang 96,15% dengan laju alir 2,5 mL/menit. Hasil menunjukkan bahwa laju alir influen, komposisi adsorben, dan pH awal larutan mempengaruhi kapasitas adsorpsi masing-masing adsorben yaitu semakin cepat laju alir maka kapasitas adsorpsi juga semakin besar, semakin besar komposisi adsorben yaitu fraksi berat
serbuk cangkang kupang maka kapasitas adsorpsinya akan semakin menurun. Pengaruh pH awal larutan terhadap kapasitas adsorpsi yaitu pH awal larutan yang diatur menggunakan pH optimum pada pH 4 memiliki kapasitas adsorpsi yang lebih besar dibandingkan dengan larutan awal tanpa pengaturan pH

In this research a composite adsorbent of kupang shell powder-chitosan cross-linked 0.2% glutaraldehyde was prepared where each material could bind Cu(II) metal continuously using a fixed-bed column system. The kupang-chitosan shell adsorbent was put into in a column with a diameter of 1.5 cm and the initial concentration of Cu(II) solution is 100 mg/L. Variations used were influent flow rates (1.5 mL/minute; 2 mL/minute; and 2.5 mL/minute), variations in the composition of the adsorbent were made in the weight fraction of mussel shell powder (93.75%; 95.24%; and 96.15%), as well as variations in the initial pH of the solution (with adjustment and without setting). At the initial pH, the unadjusted solution was used specifically for the adsorbent composition with a weight fraction of 96.15% mussel shell powder at a flow rate of 2.5 mL/minute. The results show that the influent flow rate, adsorbent composition, and initial pH of the solution affect the adsorption capacity of each adsorbent, namely the faster the flow rate, the greater the adsorption capacity, the greater the adsorbent composition, namely the weight fraction
Kupang shell powder, the adsorption capacity will decrease. The effect of the initial pH of the solution on the adsorption capacity is the initial pH of the solution which is adjusted using the optimum pH at pH 4 has a greater adsorption capacity than the initial solution without pH adjustment
