The biosorption characteristics of Cu(II) ions from aqueous solution using Lobaria pulmonaria (L.) Hoffm. biomass were investigated. The biosorption efficiency of Cu(II) onto biomass was significantly influenced by the operating parameters. The maximum biosorption efficiency of L. pulmonaria was 65.3% at 10 mg/L initial metal concentration for 5 g/L lichen biomass dosage. The biosorption of Cu(II) ions onto biomass fits the Langmuir isotherm model and the pseudo-second-order kinetic model well. The thermodynamic parameters indicate the feasibility and exothermic and spontaneous nature of the biosorption. The effective desorption achieved with HCl was 96%. Information on the nature of possible interactions between the functional groups of the L. pulmonaria biomass and Cu(II) ions was obtained via Fourier transform infrared (FTIR) spectroscopy. The results indicated that the carboxyl (-COOH) and hydroxyl (-OH) groups of the biomass were mainly involved in the biosorption of Cu(II) onto L. pulmonaria biomass. The L. pulmonaria is a promising biosorbent for Cu(lI) ions because of its availability, low cost, and high metal biosorption and desorption capacities.
Lobaria pulmonaria is a promising biosorbent for Cu(II) ions because of its availability, low cost, and high metal biosorption and desorption capacities. To the best of our knowledge, this is the first paper on the biosorption Cu by L. pulmonaria.
本研究考察了利用肺衣（Lobaria pulmonaria（L.）Hoffm.）生物质从水溶液中吸附 Cu(II)离子的特性。操作参数对 Cu(II)离子在生物质上的吸附效率有显著影响。在初始金属浓度为 10mg/L、生物量投加量为 5g/L 的条件下，肺衣对 Cu(II)的最大吸附效率为 65.3%。Cu(II)离子在生物质上的吸附较好地符合朗缪尔等温吸附模型和准二级动力学模型。热力学参数表明了吸附的可行性以及吸附的放热和自发特性。用 HCl 进行有效解吸可达到 96%。通过傅里叶变换红外（FTIR）光谱获得了关于肺衣生物质的官能团与 Cu(II)离子之间可能相互作用性质的信息。结果表明，生物质中的羧基（-COOH）和羟基（-OH）基团主要参与了 Cu(II)离子在肺衣生物质上的吸附。由于其可用性、低成本以及较高的金属吸附和解吸能力，肺衣是一种很有前途的 Cu(II)离子生物吸附剂。
