| Abstract: | Various extraetants were applied for extraction of Boron from solid waste, and the obtained extracts were analyzed by Azomethine-H spetrophotometric melhod. The result showed that aqueous acetic acid with pH=2.64 ± 0.05 has better extraction rate than others. The effeets of developing time, plt value, metal ion and operating conditions were studied. The results gained under optimum condilion indicated that addition recovery was between 87%- 103%. Comparison with ICP-AES method shows that this method is reliable and the accmacy is suitable. |
