Tables for Chapter 3 -Sorption of hydrophobic organic compounds

 

Table 1. The K_d values for the whole sand, the coatings, the naked sand, the sonicated sand but without separation of coatings and the sand without iron compounds. Samples 1 and 5 from Port Jefferson and samples 6 and 7 from South Setauket.

 

 

Table 2. Fraction of the coatings to the whole coated sand mass. Medium-coarse coated sand from Port Jefferson (samples 1 and 5) and coarse sand from South Setauket (samples 6 and 7).

 

Table 3. The estimation of the contribution of the naked sand (f _{naked sand} * K_{d naked sand}) and the coatings (f _coatings * K_{d coatings}) to the sorption of the whole sand from Port Jefferson (samples 1 and 5) and South Setauket (samples 6 and 7).

 

 

 

Table 4. Fraction of organic carbon (TOC) measured on the whole sand, the coatings and the naked sand and estimated for the coatings. Coated medium-coarse sand from Port Jefferson (samples 1 and 5) and coated coarse sand from South Setauket

(samples 6 and 7).

 

 

Table 5. Surface area measured on the whole sand, the coatings and the surface area contribution that coatings make to the whole coated sand form Port Jefferson (samples 1 and 5) and South Setauket (samples 6 and 7).

 

Table 6. The comparison among the log K_oc whole sand, log K_oc coatings, log K_oc naked sand and predicted log K_oc. Samples 1 and 5 (Port Jefferson) and 6 and 7 (South Setauket).

 

 

Table 7. The comparison between the experimental and the predicted K_sa values for the whole sand. Samples 1 and 5 (Port Jefferson) and 6 and 7 (South Setauket). Surface area and K_d for porous silica, alumnia and kaolinite for calculation of predicted K_sa were taken from (Schwazenbach, et al., 1993).
