Abstract
Industrial activities are currently growing rapidly, especially the textile industry. Where the textile industry produces heavy metal waste, one of the hazardous heavy metals that are often found from textile waste is Cu(II) and Cd(II) ions. Ion absorption Cu(II) and Cd(II) are carried out by adsorption method using adsorbents of coconut fiber activated carbon using Plackett Burman experimental design. This study aims to determine the influential parameters using Plackett Burman^ s design. Selection of 9 parameters to the response that is analyzed with AAS is used for the absorption of ionss Cu(II) and Cd(II) including particle size, contact time, stirring speed, temperature, pH, Volume, concentration Cu(II), adsorbent and concentration Cd(II). In addition, to know the ability of coconut coir adsorbents in absorbing ion Cu(II) and Cd(II) in textile waste. Condition obtained through selection on parameters that affect the absorption of ions Cu(II) and Cd(II) using plackett burman design that all parameters tend to influence a separation, Adsorbent ability of coconut fiber in absorbing ion Cu(II) and Cd(II) in textile waste obtained Activated carbon coconut fiber absorbs 25.26 % ion Cu(II) with absorption capacity of 0.42 mg/g, while ion absorption Cd(II) has absorption efficiency of 46.46% with absorption capacity of 0.98 mg/g.
