“…The drastic reduction of the CEC causes the soil infertility by the reduction of water and nutrients retention in clay soils. 21 This negative impact did not occur in soils rich in kaolinite (P) and should not occur in soils in cold climates, rich in sand.…”

“…15 Fenton's reagent is a chemical oxidizing agent commonly used in the remediation of contaminated soils. [15][16][17][18][19][20] This process is based on the reaction between 16 Side-effects of oxidation processes on soil quality have been investigated only through the analysis of toxic metabolites. The effect of oxidant on soil organic matter is also highly reported.…”

“…The effect of oxidant on soil organic matter is also highly reported. 21 However, there is not enough information on the oxidation effect on mineralogical and some physicochemical soil properties. This is relevant considering soil fertility.…”

“…Sirguey et al 21 applied Fenton's reagent to a cambisol collected in France and found a significant decrease in organic carbon in soils and a reduction of soil CEC directly linked to the mineralization of organic matter. These authors also observed that, after the application of the technique, seedling growth was slower in the treated soil samples than in the untreated ones.…”

Neste trabalho, foram avaliados os impactos na composição mineralógica e nas propriedades físico-químicas de duas categorias representativas de solos brasileiros -um vertissolo (V) e um argissolo (P) -após tratamento com reagente de Fenton. Os argilominerais presentes no V, rico em argilas expansivas, sofreram degradação após o tratamento pelo reagente de Fenton. No solo P, rico em caulinita, não foi observada nenhuma alteração significativa na mineralogia de sua fração argila após este tratamento. A capacidade de troca catiônica (CTC) de V foi drasticamente diminuída, o que em longo prazo poderá causar a infertilidade do solo por causa da redução da sua capacidade de retenção de água e nutrientes.In this work, the impacts on the mineralogical composition and on the physico-chemical properties of two representative categories of Brazilian soils -a vertisol (V) and a kandiudult (P) -after treatment with Fenton reagent were studied. The clay minerals presented in the V (rich in 2:1 expansive clay) have been degraded with this reagent application. In the other, P, rich in kaolinite, there was no significant change in its clay mineralogy after this treatment. Furthermore, the cation exchange capacity (CEC) of V was dramatically diminished and consequently can cause the soil infertility by the reduction of water and nutrients retention.

“…Adicionalmente, Sirguei e colaboradores 54 57 o processo de degradação no solo é comandado por processos de dessorção-oxidação. Desta forma, se a dessorção do contaminante ocorre mais rapidamente que a sua oxidação, a lixiviação destes compostos para os corpos hídricos é favorecida.…”
