Synthesis of Eco-friendly (PAMC): The de-oiled mustard cake (DOMC) samples were taken from a local mill and it was crushed in a pestle and motors. The material was washed several time with distilled water until colorless and then sundried. The DOMC was treated with H2O2 at 60 °C for 24 h to oxidize the adhering organic matter. The resulting material was washed several times using double distilled water. The powder was dried at 110°C overnight and it was then burnt in Muffle furnaces at 715°C 25 min in the absence of air. The material was grounded and sieved to desired particles sizes.
