The aim of this study was to investigate the effect of Moringa Seed Pod Powder (MSPP) as a biosorbent on the biosorption of Pb2+ and Cu2+ influenced by pH, contact duration, dosage, and extracting solution concentration. Soil samples were collected using a soil auger at depths ranging from 0 to 20 cm using a systematic (grid) sampling procedure. Moringa seed pod samples were air-dried in the shade, crushed with a stainless steel mortar and pestle, regrind with an electric grinder, and sieved (2-mm). The influence of pH on metal adsorption capacity was divided into three phases: slightly acidic, neutral, and alkaline. The adsorption of Cu2+ and Pb2+peaked in alkaline conditions, with values of 85.71% and 99.13%, respectively, and was lowest in neutral soil pH for both metals. The adsorption of Pb2+ gradually increases as the dose and shaking time change from 2 g for 2 h (97.20%) to 4 g for 4 h (98.81%), where it reaches a maximum, and then slightly drops as the dose and shaking time increase to 6 g and 6 h (98.14%). While Cu2+ exhibits a substantial drop in adsorption from 89.09% at (2 g 2 h) to 84.65% at (4 g 4 h), it rapidly increases to 89.99% (6 g 6 h), which represents the maximum adsorption. It is recommended to use moringa seed pod powder for the removal or remediation of Pb2+ and Cu2+ polluted soils.
