摘要: The aim of this study was to evaluate the biochar characteristics derived from fruit tree pruning wastes (FTPW) and their effects on lead (Pb) adsorption. Based results Pb adsorption, surface area, phosphorus content, optimum pyrolysis temperature 600 °C for adsorption capacity. Using Freundlich isotherm, capacity (K) obtained various FTPW decreased in order pear (3.8001) ≫ persimmon (2.3977) ≥ apple (2.1968). Langmuir maximum capacities (a; mg g−1) different were following order: (26.2) ≫ persimmon (19.9) ≥ apple (17.7). pruned waste greater than other biochars. Pruned apple had lowest among tested positive correlation between (L M) values biochars content area indicated difference However, all studied could be used removing metal wastewater.
