When the reaction was complete, the color of the methanol solution of palladium dichloride changed from red-brown to pale brown as a result of palladium(II) loss to the fiber. After the coordination reaction, the fiber was extracted with methanol for at least 24 h at room temperature to remove any palladium complex that was not chemically bonded to the fiber. The fiber was deep-brown in color and contained 0.576 mmol/g palladium after drying in vacuo.
