     The amount of desorption of Cd increased with increasing pH and amount of Cd adsorption. However, the proportion of Cd desorption to adsorption decreased with pH. At pH 3-7, the ratio of desorption to adsorption of Cd in yellow brown earth was 42%~95% with average 75%, which indicated that Cd was mainly nonspecifically adsorbed by yellow brown earth and the availability of Cd adsorbed was high.

紫色土中Cr(Ⅵ)的吸持量因土壤基本化学性质不同而存在较大的差异,游离铁及pH是影响最大吸持量的主要因子,“双表面”Langmuir模式最适宜于描述紫色土中Cr(Ⅵ)的吸持作用。酸性紫色土中,由于羟基交换、形成双核络合物等作用,吸持达到平衡的时间较长;中性及石灰性紫色土中,吸持作用在极短时间内即可达到平衡点。酸性紫色土中吸持Cr(Ⅵ)的解吸量及解吸率都比中性紫色土高。酸性紫色土在整个吸持区内都存在专性吸附,中性紫色土在低吸持区以非专性吸附为主,高吸持区伴有专性吸附。

In this article, NO, and SO42- adsorption isotherms on red soil developed from Quaternary Red Clay in southern Hunan Province were studied. The results showed that NO3- adsorption by the soil was negetive when concentrations of NO3- in the equilibrating solution were low, but it was positive when the concentrations were higher. The mechanism of the NO3-adsorption was non-specific. However, the most suitable isotherm equation for describing SO42- adsorption by the soil was Freundlich equation, and it was suggested...

In this article, NO, and SO42- adsorption isotherms on red soil developed from Quaternary Red Clay in southern Hunan Province were studied. The results showed that NO3- adsorption by the soil was negetive when concentrations of NO3- in the equilibrating solution were low, but it was positive when the concentrations were higher. The mechanism of the NO3-adsorption was non-specific. However, the most suitable isotherm equation for describing SO42- adsorption by the soil was Freundlich equation, and it was suggested by the authors that most of the sulphate had been adsorbed by red soil with a specific adsorption mechanism through the displacement of hydroxyl ion (-OH) in the surface of soil particals before achieving the maximum value of SO42-- adsorption (Xm) by the soil, while beyond which a non-specific physics adsorption mechanism was the prevalent mechanism.

本文研究了湘南第四纪红粘土发育的红壤对NO_3和SO_4~(2-)的吸附等温线。结果表明红壤对NO_3~-的吸附在浓度低时为负吸附,浓度高时为正吸附,吸附机理为非专性吸附,红壤对SO_4~(2-)的吸附等温式以Freundlich方程最好,在达到最大吸量(X_m)之前,SO_4~(2-)以置换羟基(—OH)的配位吸附为主;而在达到最大吸附量以后,以非专性物理吸附为主。

Adsorption of Mn2+ onto birnessite is very rapid and amounts adsorbed are several times higher than its cation exchange capacity. The nature and fate of the adsorption, however, were not well understood. Thus experiments were conducted to investigate the mechanism of adsorption of Mn2+ onto a synthetic birnessite and effects of three Mn-salts (MnSO4, MnCl2 and Mn(NO3)2) on mineralogical alteration of birnessite.The results indicated that adsorption of Mn2+ onto birnessite included both specific and non specific...

Adsorption of Mn2+ onto birnessite is very rapid and amounts adsorbed are several times higher than its cation exchange capacity. The nature and fate of the adsorption, however, were not well understood. Thus experiments were conducted to investigate the mechanism of adsorption of Mn2+ onto a synthetic birnessite and effects of three Mn-salts (MnSO4, MnCl2 and Mn(NO3)2) on mineralogical alteration of birnessite.The results indicated that adsorption of Mn2+ onto birnessite included both specific and non specific adsorption. The adsorbed Mn2+ was incorporated into the structure of birnessite and its extrability by salts decreased with time of aging. After reaction of birnessite with MnCl2 or Mn (NO3)2 solution, incorporation of Mn2+ into he structure caused transformation of birnessite into nsutite (Mn oxide hydroxide, γ-Mn (O, OH)2). In the solution of MnSO4, birnessite was convened into nsutite and a larger quantity of ramsdellite (Mn oxide, MnO2) . Both newly formed minerals are more stable and better crystallized than birnessite. Thus the Mn2+ initially adsorbed onto birnessite became the component of the newly formed minerals and was fixed in the structure after structural conversion of birnessite and finally lost its extractability and availability.

本试验研究了一种合成水钠锰矿对Mn~(2+)的持留机理和Mn~(2+)被吸附后的去向,并进一步探讨了三种锰盐溶液(MnSO_4,MN(NO_3)_2和MnCl_2)对水钠锰矿晶体结构变化的影响。 试验结果表明,水钠锰矿对MN~(2+)离子的吸附包括专性吸附和非专性吸附。随着吸附后的老化过程,吸附在矿物表面的锰逐渐扩散到晶格内,其置换性随之降低。 在MnSO_4,Mn(NO_3)_2和MnCl_2溶液中,水钠锰矿最终转化成六方锰矿(Nsutite),一种比水钠锰矿更稳定,结晶更好的晶体。MnSO_4溶液在加入水钠锰矿后pH值比其它两种溶液高,除生成六方锰矿外还形成大量拉锰矿(Ramsdellite)。随着生成新矿物的老化,最初被吸附的Mn被固定在晶格内而失去其置换性和生物有效性。
