abstract introduction: due to environmental and human health concerns related to humic acid (ha), mainly leading to disinfection by-products creation, removal or reduction of this matters is a necessary for drinking water suppliers. based on resistive economy map road and move to self-sufficiency, it is necessary to produce our need in water treatment industry. one of the main consumed material...

results the batch kinetics experiments showed that nom adsorption by the adsorbents followed the pseudo-second order model. results showed that the acidic ph is optimum for adsorption of nom by smz. conclusions the findings of this study show that natural zeolite modified with sodium dodecyl sulfate, as a cationic surfactant, is a promising adsorbent for removal of nom. materials and methods in...

conclusions the findings of this study showed that the modification of natural zeolites can achieve higher adsorption capacity for organics. in addition, based on the results, natural zeolite being modified with sds as a cationic surfactant had good efficiency for the adsorption of nom. results the results indicated that sds-modified zeolite showed greatly enhanced adsorption capacity. findings...

Natural organic matter (NOM) affects some qualitative parameters of water such as color. In addition, it can deteriorate the performance of water treatment process including coagulation, adsorption, and membranes. NOM also reacts with chlorine in the chlorination process and may form disinfection by-products. The present study was carried out in laboratory-scale in a batch system using a cylind...

land cover change constitutes one of main way of alteration of soil organic matter in both quantitative and qualitative terms. the goal of this study was to compare the carbon stock and the isotopic signature of the organic matter in the soil of areas with different land use, covered with forest and grass (pasture). the study area is located at sorocaba, sp, brazil. using un-deformed soil sampl...
