Abstract: In phosphate-producing countries (United States, Commonwealth of Independent States, North and West Africa including Senegal), the presence of phosphate ores (hydroxyapatite) is often associated with that of fluorine ores (fluoro apatite). In these regions, water from confined aquifers may have excessive fluoride contents. While the potability stan... Show More

Abstract: The adsorption of Pb²⁺, Cu²⁺ and Cr³⁺ from aqueous solution using Neem seed husk (NSH) and baobab seed (BS) were studied through the use of batch adsorption system. The adsorbents were prepared by drying at 120°C for 24hours and were characterized using FT-IR, XRD, and SEM analysis. The FTIR spectroscopy revealed the presence of O-H, N-H, C-H, C=C,... Show More
