GRATED COCONUT RESIDUE MODIFIED BY A CATIONIC SURFACTANT FOR REMOVAL OF REACTIVE ORANGE 16 DYE; [Sisa Kelapa Parut Diubahsuai oleh Surfaktan Kationik untuk Menyingkirkan Pewarna Reaktif Oren 16]

Hexadecylpyridinium chloride monohydrate, a cationic surfactant, was employed to chemically modify coconut-grated residue to adsorb reactive orange 16 (RO16). The pH point of zero charge (pHPZC) and surface area were used to characterise the raw coconut grated residue (RGC) and the surfactant-modifi...

Hexadecylpyridinium chloride monohydrate, a cationic surfactant, was employed to chemically modify coconut-grated residue to adsorb reactive orange 16 (RO16). The pH point of zero charge (pHPZC) and surface area were used to characterise the raw coconut grated residue (RGC) and the surfactant-modified grated coconut residue (SMGC). The pHPZC was 5.5, and the Brunauer-Emmett-Teller surface area was 1.86 m2 g-1. The dye solution pH and dose effects on RO16 adsorption were tested in a batch adsorption system. Maximum sorption was seen at an SGMC concentration of 10 g L-1, while optimal adsorption was observed at a low pH. When dye-loaded SGMC was exposed to a basic solution, the desorption percentage increased to almost 70%, whereas low desorption was observed under acidic conditions. Furthermore, the isotherm study discovered that the Freundlich model explained RO16 adsorption of SMGC better than the Langmuir model. The Langmuir isotherm recorded a maximum adsorption capacity of 9.72 mg g-1. © 2023, Malaysian Society of Analytical Sciences. All rights reserved.
