Study on the Adsorption of Iron Ion by Nano-Al2O3 and the Growth Effect on Microalgae [PDF]
, 2016 本文首先研究了海水体系中纳米Al2O3对Fe离子的吸附过程，通过单因素和正交试验探讨了Fe初始浓度、海水pH和盐度等因素对吸附过程的影响。其次，以普通小球藻和球等鞭金藻为受试对象，用藻体的叶绿素a含量、蛋白质含量、超氧化物歧化酶（SOD）活性和丙二醛（MDA）含量为指标，研究了不同浓度和粒径的纳米Al2O3、与Fe共存的纳米Al2O3对海洋微藻的生长效应。主要结论如下： （1）纳米Al2O3对铁离子吸附的平衡时间为15min，为准二级反应吸附，平衡吸附量qe为8.55mg/g。同等条件下（25°C ...

Rare Metals, EarlyView.ABSTRACT Developing low‐energy‐input electrocatalytic systems for efficient hydrogen production is crucial for advancing sustainable energy technologies. The overall hydrazine splitting (OHzS) has emerged as a promising strategy to reduce the overall energy consumption by replacing the sluggish oxygen evolution reaction.

Rare Metals, EarlyView.ABSTRACT Converting CO2 to CH4 under mild conditions is a promising strategy for solving environmental and energy problems, but also a challenge. In this work, the low‐temperature CO2 hydrogenation process over Ni/CeO2 catalysts was significantly accelerated by optimizing the H2 dissociation ability of Ni through the size effect, thus A‐Ni/CeO2 with an

Shuitu Baochi Xuebao, 2016 为了探究Pb在底泥和土壤中的吸附行为，通过OECD guideline 106平衡吸附法，来探讨Pb在底泥和土壤中的吸附特性以及不同pH、有机质和N、P含量对Pb吸附特性的影响。结果表明：Temkin模型能够更好地拟合底泥对Pb的吸附，r=0.925；Freundlich能够更好地拟合土壤对Pb的吸附，r=0.971。Pb在15，25，35 ℃下吸附条件下，温度升高会促进底泥和土壤对Pb的吸附，ΔＧ＜0，ΔＨ＞0，说明底泥和土壤对Pb吸附为自发的吸热反应；在pH为3～11的条件下 ...

Rare Metals, EarlyView.ABSTRACT Early detection of thermal runaway (TR) is essential for lithium‐ion battery (LIB) safety, as unchecked TR risks catastrophic failures in energy storage systems. Gas‐based sensing offers a faster and more direct approach by detecting decomposition products at the molecular level.

Shuitu Baochi Xuebao, 2006 聚丙烯酰胺（PAM）在农业上作为扰侵蚀剂、保水剂被广泛应用，但施用后对土壤养分保持和释放的影响研究较少。本文采用向土壤（塿土）中添加不同比例（0．1％，0．2％，0．4％占土壤的比例）的PAM溶液，通过磷素等温吸附解吸试验，探讨了PAM对磷素在土壤中吸附和解吸的影响。结果表明。和原土样相比．土壤经PAM处理后抑制了土壤对磷的物理吸附，导致吸附量减小．最大吸附量（Xm）降低，而对磷素在土壤中的化学吸附影响较小．被吸附磷尤其是物理吸附磷的解吸率升高。

Adsorption of Selemiun and Cr(VI) and rapid detection of Cr(VI) in aqueous solution using composite materials based on fuctionalizing bentonite [PDF]
, 2015 随着工业化程度的不断提高，环境中重金属污染日益严重。由于重金属不可生物降解的特性，在水体中富集就造成水域环境污染；通过食物链在人体中富集，则危及人类身体健康。硒是人体必需的微量元素，适量硒具有增强机体免疫功能，抗氧化和防癌作用。但是，摄人过高或过低的硒元素均会对人体健康造成危害，反而具有致突变和癌变作用。水体中的硒元素污染主要由于人类对矿物的过度开采以及一些工业生产部门的废水乱排造成的。水域中重金属铬污染主要来源于铬矿的采选矿、造纸、印刷、冶炼电镀、染料、机器制造、制药等工业部门排出的废水。其中 ...

Rare Metals, EarlyView.ABSTRACT The detection of volatile organic compounds (VOCs) holds significant implications in environmental monitoring and disease diagnosis. Traditional gas detection technologies are constrained by complex operation and high cost, thereby failing to satisfy real‐time detection demands.
