dc.description.abstract
Experimentos do fluxo da água usando um meio poroso não saturado compoto por diferentes sistemas de a- alumina molhada não-saturada indicam que a carga superficial da partícula diminuiu com o aumento da água movimentada. O movimento máximo de água ocorreu quando a carga superficial era zero. O movimento da água foi afetado pela espessura da dupla camada elétrica no pH em que as partículas têm carga líquida (a partir do IEPpH). Estes resultados sugerem estruturação da água, induzida por carga, adjacente a superfícies de partículas carregadas.  
dc.description.abstract
Experiments of water flow using a non saturated porous medium constituted by different a- wet unsaturated alumina systems indicate that particle surface charge decreased the amount of water moved. Maximum water movement occurred when surface charge was zero. Water movement was affected by thickness of the electrical double layer at pH where particles have net charge (out of the IEPpH). These results suggest charge-induced structuring of water adjacent to charged particle surfaces.
