"Application of Rawa Pening peat soil humic acid for adsorption-reduction\r\nof Au(III) have been investigated. The purpose of this researched is to know the\r\nability of humic acid to adsorption and reduction of Au(III).\r\nThis research was started by purification of humic acid with HCl/HF\r\nsolution. The purified humic acid was characterized by FTIR spectroscopy, ash\r\ncontent, total acidity, -COOH content, and –OH content, then applied for\r\nadsorption reduction of Au(III).The Effect of pH adsorption, adsorption kinetics,\r\nand adsorption isotherm on adsorption reduction process of Au (III) also were\r\nstudied. The gold metal formed was confirmed by IR spectra and photo optical\r\nmicroscope..\r\nThe result showed that purified humic acid has 11,32% ash content, total\r\nacidity of 685 cmol/kg, -COOH content of 237 cmol/kg, and -OH fenolaic content\r\nof 448 cmol/kg. The adsorption-reduction of Au(III) ion on humic acid was\r\nmaximum at pH 3. KF value of adsorption Au(III) on humic acid determined\r\naccording to Freundlich isotherm model were 21,42 mg/g, adsorption energy\r\n7,644 kJ/mol < 10 kJ/mol (physisorption) and the adsorption rate constant (k)\r\ndetermined according to Santosa kinetic model for humic acid are 0.002 min-1,\r\nrespectively"^^ .
