Abstract

Alkaline-treated natural zeolite was prepared by sodium hydroxide treatment of natural zeolite and applied in the adsorption of Pb(II). The response surface methodology (RSM) analysis was conducted under manipulated variables of initial concentration (X₁ = 50–400 mg/L), pH (X₂ = 2–10), and adsorbent dosage (X₃ = 0.5–5.0 g/L). The optimal condition was attained at X₁ = 240 mg/L, X₂ = 6, and X₃ = 1.07 g/L, with Pb(II) removal of 60.75 %. The characterization of alkaline-treated natural zeolite of fresh and spent confirmed the adsorption of Pb(II) onto alkaline-treated natural zeolite. The reusability and regeneration experiments revealed the ability of the alkaline-treated natural zeolite in multiple cycles of the adsorption process. This study proved that alkaline-treated natural zeolite could be an alternative low-cost adsorbent for wastewater treatment containing Pb(II).

碱处理天然沸石吸附水中铅(II):工艺优化分析

采用氢氧化钠处理天然沸石制备碱处理天然沸石，并将其用于吸附Pb(II)。在初始浓度(X1 = 50 ~ 400 mg/L)、pH (X2 = 2 ~ 10)、吸附剂投加量(X3 = 0.5 ~ 5.0 g/L)条件下进行响应面法(RSM)分析。最佳条件为X1 = 240 mg/L, X2 = 6, X3 = 1.07 g/L, Pb(II)去除率为60.75%。对碱处理过的天然沸石的新鲜和废沸石进行了表征，证实了碱处理过的天然沸石对Pb(II)的吸附。实验结果表明，经碱处理的天然沸石具有多次循环吸附的能力。本研究证明碱处理的天然沸石可作为一种低成本的吸附剂处理含铅废水。
