Sugarcane and Water Hyacinth Provide Affordable Carboxymethyl Cellulose for Zimbabwean Mines
The scientists found a way to make carboxymethyl cellulose (CMC) from sugarcane leftovers and water hyacinth. This special cellulose is important for some mining activities in Zimbabwe, like platinum mining, and usually needs to be imported from other countries like China, which is costly. They extract cellulose from these plants by removing certain parts to make it. To turn this cellulose into CMC, they used a process involving chemicals like sodium hydroxide and monochloroacetic acid. The best concentration of sodium hydroxide to start the process was found to be 30%. The success of the method was confirmed using tests like potentiometric back titration and infrared spectroscopy. The researchers got a high yield of around 85.2% from this process.
