Adsorption Properties of Au(III) and Cu(II) from Aqueous Solution Using Chemically Treated Sheep Wool

Au(III) and Cu(II) adsorption from aqueous solution were carried out using sheep wools with chemical treatments, by NaOH, Na2S, NaHSO3, and NaBH4 aqueous solution. The fibrous wool was transformed into a film like structures after the chemical treatment using Na2S. The sheep wool and the chemically treated sheep wool adsorbed selectively Au(III) from Au-Cu binary aqueous solution and the presence of copper ion had no effect on the Au(III) adsorption. Au(III) adsorbed substantially at low pH range. The kinetic experimental data fitted well with the pseudo-second-order kinetic model and the adsorption amount of Au(III) increased with time and reached a plateau after 12 h. The kinetic analysis suggests that rate determining step of Au adsorption would be chemisorption due to the formation of a monolayer on the wool surface. Sheep wool is a low cost, eco-friendly material, and has a high capacity of adsorption, and could be used as a biosorbent for precious and heavy metals by modification of appropriate chemical treatment.conference pape

Global Relation Between the Steady State Rate Mode and the Transient State Behavior of Products*

application/pdfA new approach has been applied to find the global relation between the mode of steady state rate function (SSF) and the transient state behavior (TSB), by using a computer simulation technique. A typical complex reaction model producing two different products in parallel in which a stable surface intermediate participant (In) is added is used as an example. The mode of the SSF is classified into three typical types according to the values of the kinetic parameters employed ; Type A : monotonous increase mode for the two products (lower surface coverage of (In), θ_＜0.1) ; Type B : the volcano mode for one and the monotonous increase mode for another product (higher surface coverage of (In), θ_=0.1-0.7) and Type C : volcano mode for the two products (θ_=0.1-0.9). The mode were sensitively characterizes by the amount of the surface intermediates and the kinetic parameters. The TSB is drastically and sensitively varied depending on the combination of the values of kinetic parameters and the surface coverage of the adsorbed species relating to the mode of the SSF. The modes of TSB are classified into four characteristic types ; Type I : Over-shoot mode which appears on a relatively lower surface coverage of (In)(θ_＜0.4) plus the slower regeneration of active species (at the low concentration region of Types A and B) ; type II : False start mode which is observed with a relatively lower surface coverage of (In) (01.-0.3) plus the inhibition effect of reactant (at the high concentration region of Type A and low concentration region of Type C) ; Type III : Extraordinarily slow response mode which appears on very slow reconfiguration of the adsorbed species (at the medium concentration region of Type C) ; Type IV : No change mode which results from the saturated coverage with the surface intermediates (at the high concentration region of Type C).departmental bulletin pape

第4節 高校1年生 サイエンスリテラシーを育成する『生命と環境』(第2章 各学年の総合人間科の取り組み, VI. キャリア形成を軸とした総合人間科の取り組み)

2010-01-25総合学習としての『総合人間科』は本校が長く取り組んできた教科である。今年度はSSHと直結させ、「サイエンスリテラシーを育成する」ことを目標とし、生徒に目標達成までのプロセスを明確にし取り組ませた。また我々は、サイエンスリテラシーの定義のうち、リテラシーの部分の目標を高１の発達段階に即して、問題化力、科学的思考力、言語表現力の３つに分類し、生徒による授業評価を行い、目標達成度を分析した。結果は言語表現力が最も高かった。departmental bulletin pape
