February 06, 2018 - biosorbent dose on the biosorption of cadmium. They learned that maximum biosorption occurred at a pH level of 5 and that it stood at 10.28 percent. Regarding contact time, they noted that the highest absorption rates occurred after the first 30 minutes, then the solution reached biosorption equilibrium at around 50 minutes.What these results mean is simply that there is now a low-cost, environmentally friendly way of removing harmful cadmium from water that only ...

August 18, 2018 - biosorbent capabilities, the Thai researchers collected samples growing near the university and put them through the viscose process. They also varied the concentration of certain ingredients used during the process (sodium hydroxide, carbon disulfide, and sodium sulfate) to determine the most efficient ratio for a natural fiber sorbent.The research team tested this natural fiber sorbent alongside the conventional polypropylene sorbent. The oils used for the ASTM ...
