*3.4. Silver Content Analysis in C. pentandra*/*Ag-NPs*

The amount of Ag-NPs deposited in *C. pentandra*/Ag-NPs was determined quantitatively using ICP-OES analysis. The amount of Ag-NPs calculated from *C. pentandra*/Ag-NPs was 40.19 g/kg while for *C. pentandra*/AgNO3, the amount of Ag-NPs calculated was only 35.47 g/kg. In the presence of *E. spiralis* extract, increased the reducing agent to the *C. pentandra* fiber for the reduction of Ag<sup>+</sup> to Ag0. Thus, increased the amount of Ag-NPs incorporated in *C. pentandra* fiber.
