| Abstract | ||
| The contamination of different water resources with various pollutants such as heavy metals, organic materials, synthetic effluents, and pesticides has become great challenge. Phytoremediation is one of the safer, economical, and environment-friendly techniques in which plants are used to recover polluted soils, particularly those containing toxic organic substances and heavy metals. An eco-friendly and clean phytoremediation technique using different sources of special plants are used in order to decrease the toxicity of these pollutants especially the biodegradable heavy metal. In the present study a novel Sahrawi boisorbent is prepared from Anabasis Articulate plant from naturally growing populations in Wadi Ash-Shaykh, North eastern Desert, Egypt as a novel Sahrawi boisorbent that was successfully used for the removal of lead metal ions from water resources. The Anabasis Articulate biosorbent (ANA) is characterized by Boehm titration, point of zero charge (pHPZC), SEM, FT-IR spectroscopy and TGA analysis. The different experimental parameters affecting the batch mode adsorption of Pb (II) onto ANA biosorbent were assisted such as pH effect, initial concentration of Pb (II) ions, contact time and adsorbent dosage of ANA biosorbent. At optimum conditions, the adsorption capacity of lead metal ions reaches 76.0 mg/gm. The adsorption process is more fitted to pseudo-second order than first-order. Adsorption isotherm studies are fitted to Langmuir. The negative values of ΔG°, and ΔS° indicated that lead adsorption on Anabasis Articulate biosorbent is spontaneous with random nature on the adsorbent-adsorbate system. . | ||
