摘要

Anthropogenic activities generate waste products, which consist of an emerging and troubling class of organic micropollutants (OMPs). These contaminants can damage human and environmental health, being present in hospitals and agricultural wastewater, with the aggravating factor of not being effectively removed in treatment plants. Of the available waste treatment technologies, adsorption appears to be the most promising, because it does not promote the formation of degradation by-products, which may exhibit a similar, or even greater, hazard to primary compounds. In this context, the present study assessed the adsorption potential of seven hormones (natural and synthetic) using two adsorbents prepared from Pinus eliotti spp. barks. An activated carbon commonly used in treatment plants was used as a control. The adsorption experiments were carried out with spiked samples at a 1 mg L~(-1) contaminant concentration, at doses of adsorbent material that are capable of removing 80% of the concentration of contaminants (D80). The materials were prepared by acidic or basic hydrolysis, being characterized by the addition of pine sulphur (PS) and potassium to their surfaces. The analysis was performed by high-performance liquid chromatography-diode-array detection. The possibility that the effect of electronegativity of the medium would interfere in the removal of the hormones was also evaluated. A comparison of the three materials showed that the activated carbon provided the most favourable outcome. However, it was found that the material containing sulphur was 58.4% less effective than the commercial material. The materials, particularly the PS, can be used to remove OMPs; however, improvements must be made. The relationships between adsorption and the characteristics of adsorbents and interferents should also be evaluated.
