摘    要: 以干土壤做气相色谱固定相,用测定气相色谱固定液相对极性的方法,测定了广州、四川云阳、太原、乌鲁木齐等地区的6种土壤相对表观极性(SRP),及其基本性质。结果表明:SRP(y)与土壤有机质含量(x1)、[O+N]含量(x2)呈正相关,与粘粒(<0.01mm)含量(x3)呈负相关,其关系式为y=54.2705+17.7698x1+0.1834x2-0.2014x3,相关系数γ分别为0.9980、0.9463、-0.8792(n=6,p<0.05);随着SRP值的增加,萘和硝基苯的有机质吸附系数K(om)下降。

关 键 词:土壤  相对表观极性  有机污染物  吸附  气相色谱

Abstract:The soil relative apparent polarity(SRP) was determined form samples of the dry soils of 6 areas in Guangzhou,Tai Yuan and others with GC stationary phase method.At the same time, the properties in the soils were measured. The results show that the SRP(y) is of positive relation to both the content(x_1) of organic matter and the sum(x_2) of oxygen and nitrogen in soil;and is of negative relation to clay(<0.01mm)(x_3)in soil as shown in the equation y=54.2705 17.7698x_1 0.1834x_2 -0.2014x_3 with the relation coefficient of 0.9980,0.9463-0.8792(n=6,P<0.05) respectively.The effect of SRP on the adsorption of naphathalene and nitrobenzene has been studied,and it is shown that the adsorption is decreased with increase of the SRP.
Keywords:Soil  Relative apparent polarity  Organic pollutant  Adsorption  GC method
