1. Preparation procedure for extracting activated carbon from water seeds (Mauritius flexuosa) by chemical treatment

摘要

It refers to a procedure to release activated carbon from seed seeds for removing heavy metal ions by using a low concentration of phosphoric acid between 10% and 14%,A circular oven, in which a stable gas nitrogen flow is circulated, and three heating ramps are (I) 200 ℃ for 30 minutes, (II) 300 ℃ for 30 minutes, and (III) 500 ℃ to 600 ℃ for 60-90 minutes, heating speed of 10 ℃ C / min, to obtain a high mechanical strength activated carbon, High performance and high metal ion adsorption capacity
