    Abstract
    Chitosan had used as absorber of iron waste (Fe2+ ) and Natrium (Na+ ) on detergent liquid waste. Nanoparticle chitosan is used to increase the effectiveness of chitosan absorption on detergent liquid waste by enlarger the surface of chitosan. FESEM analysis found that Nanoparticle chitosan is larger and smooth in the value of 80 nm. The spectroscopic analysis of FTIR (Fourier Transform Infra-Red) indicates that the wave length N – H = 3425.6 cm¯¹ ; C – H = 2877.8 cm¯¹ ; C = O = 1651.1 cm¯¹ ; C – N = 1381.0 cm¯¹. Variation of Nanoparticle chitosan concentration is effective for absorption of iron (Fe2+ ) and Natrium (Na+ ). The absorption of Nanoparticle chitosan on Fe is optimum on concentration of 0.8 gram/liter for 97.03% and Na on concentration of 0.8 gram/liter for 96.43%.
     
    Kitosan telah digunakan sebagai penyerap (absorbsi) limbah logam besi (Fe2+ ) dan natrium (Na+) pada limbah cair detergen. Kitosan Nanopartikel digunakan untuk mengefektifkan daya serap (adsorbsi) kitosan terhadap limbah cair detergen dengan cara memperluas permukaan kitosan tersebut. Analisa FESEM didapatkan permukaan kitosan nanopartikel yang lebih besar dan merata dengan nilai 80 nm. Analisa spektroskopi FTIR (Fourier Transform Infra-Red) menunjukkan bahwa panjang gelombang N – H = 3425.6 cm ¯¹ ; C – H = 2877.8 cm¯¹ ; C=O = 1651.1 cm¯¹ ; C – N = 1381.0 cm¯¹. Variasi konsentrasi larutan kitosan nanopartikel tersebut efektif untuk menyerap (mengadsorbsi) logam besi (Fe2+ ) dan natrium (Na+ ). Daya serap kitosan nanopartikel pada logam Fe optimum pada konsentrasi 0.8 gram/liter sebesar 97.03% dan logam Na pada konsentrasi 0.8 gram/liter sebesar 96.43%.
