Novelty statement This manuscript entitled “Elucidation of adsorption mechanism of Pb(II) onto lobeira fruit (Solanum lycocarpum) using a Langmuir, Freundlich and Temkin isotherms” by Cleide Sandra Tavares Araujo et al. describes the sorption potential of lobeira fruit (Solanum lycocarpum) for removing Pb(II) from aqueous solution using a factorial experimental design as optimization strategy and Langmuir, Freundlich and Temkin models have been used to fit adsorption isotherms. The Solanum lycocarpum known popularly as “lobeira-do-cerrado”, wolf fruit or “jurubebao”, is a lignocellulosic typical species of the “cerrado” (kind of Brazilian savannah), with wide distribution, mainly in anthropized areas, has been little explored for adsorption studies. The optimization using a factorial design enabled the optimization of the procedure to be carried out with a reduced number of experiments, thus requiring a lower quantity of reagents and showed has advantages, such as, the low cost of sorbent, high efficiency and the minimization of chemical sludge. So allowed the adsorption of lead by lobeira fruit an inexpensive and easily available raw material may be used for different industrial applications to lower the cost of wastewater treatment and has potential applications for the removal of Pb(II) from wastewater. The sorbent is an alternative material for chemical remediation and is economic and environmental friendly.

使用 Langmuir、Freundlich 和 Temkin 等温线阐明 Pb(II) 吸附到 lobeira 果实 ( Solanum lycocarpum ) 上的机制

新颖性声明 Cleide Sandra Tavares Araujo 等人撰写的题为“使用 Langmuir、Freundlich 和 Temkin 等温线阐明 Pb（II）在 lobeira 果实（Solanum lycocarpum）上的吸附机制”的手稿。描述了使用析因实验设计作为优化策略和 Langmuir、Freundlich 和 Temkin 模型来拟合吸附等温线的 lobeira 果实（Solanum lycocarpum）从水溶液中去除 Pb(II) 的吸附潜力。Solanum lycocarpum 俗称“lobeira-do-cerrado”、狼果或“jurubebao”，是“cerrado”（一种巴西大草原）的木质纤维素典型物种，分布广泛，主要在人类化地区，很少用于吸附研究。使用因子设计的优化使得可以通过减少实验次数来进行程序优化，从而需要更少的试剂，并显示出吸附剂成本低、效率高和最小化等优点。化学污泥。因此，通过 lobeira 果实吸附铅是一种廉价且易于获得的原材料，可用于不同的工业应用，以降低废水处理成本，并具有从废水中去除 Pb(II) 的潜在应用。吸附剂是化学修复的替代材料，经济环保。高效率和化学污泥的最小化。因此，通过 lobeira 果实吸附铅是一种廉价且易于获得的原材料，可用于不同的工业应用，以降低废水处理成本，并具有从废水中去除 Pb(II) 的潜在应用。吸附剂是化学修复的替代材料，经济环保。高效率和化学污泥的最小化。因此，通过 lobeira 果实吸附铅是一种廉价且易于获得的原材料，可用于不同的工业应用，以降低废水处理成本，并具有从废水中去除 Pb(II) 的潜在应用。吸附剂是化学修复的替代材料，经济环保。
