通过将粒化高炉或转炉钢渣与制浆造纸工业的残留物以不同的配方结合，研究了工业残留物在土壤中的施用。样品分析包括相关理化性质、总元素浓度（HCl+ HNO 3消化，USEPA 3051）和所选重金属的化学形态（CH 3COOH、NH 2 OH·HCl和H2 O2 + H2 O2 + CH 3COONH 4，BCR法）。生产的矩阵显示出石灰的影响，商业地面石灰石，包括大量的可溶性重要营养素。然而，转炉钢渣的使用导致Cr和V的总浓度显著增加。随后，通过Na 2CO 3 +NaOH消化，然后通过IC UV/VIS-PCR（USEPA 3060 A）证实总Cr以Cr（III）形式出现。此外，80.6%的Cr（370 mgkg −1，d.w.）发生在残余部分中。然而，46.0%的V（2470 mgkg −1，d.w.）发生在容易减少的部分，表明潜在的生物利用度。
Industrial residue application to soil was investigated by integrating granulated blast furnace or converter steel slag with residues from the pulp and paper industry in various formulations. Specimen analysis included relevant physicochemical properties, total element concentrations (HCl+HNO3digestion, USEPA 3051) and chemical speciation of chosen heavy metals (CH3COOH, NH2OH·HCl and H2O2+H2O2+CH3COONH4, the BCR method). Produced matrices showed liming effects comparable to commercial ground limestone and included significant quantities of soluble vital nutrients. The use of converter steel slag, however, led to significant increases in the total concentrations of Cr and V. Subsequently, total Cr was attested to occur as Cr(III) by Na2CO3+NaOH digestion followed by IC UV/VIS–PCR (USEPA 3060A). Additionally, 80.6% of the total concentration of Cr (370mgkg−1, d.w.) occurred in the residual fraction. However, 46.0% of the total concentration of V (2470mgkg−1, d.w.) occurred in the easily reduced fraction indicating potential bioavailability.
