Rejuvenescimento facial: peeling de fenol atenuado / Face anti-ageing: profound phenolmethod

O objetivo do presente estudo é descrever a técnica de peeling de fenol pré-oxidado, os principais cuidados pré e pós-operatórios e a avaliação dos resultados obtidos em quatro pacientes submetidos ao método, breve comparação com o método de fenol profundo tradicional de Backer e Gordon.Apresenta-se, ainda.Ao final, conclui-se que o método de peeling de fenol pré-oxidado, sem a necessidade de máscaras oclusivas, é seguro, reprodutível e demonstra um alto grau de aceitação no grupo submetido ao tratamento.

The objective of the present work is to describe the techniques of phenol peeling, the main pre-peeling and post-peeling care and the evaluation from this method of the results obtained by four patients. Comparison with Backer and Gordon traditional profound phenol method. Finally, the conclusion is that the profound phenol peeling method which doesn't use occlusive mascara is secure, reproducible and shows a real acceptance in the group submitted to the treatment.

Biosorption of phenol from aqueous solution by biosolids

Studies on the removal of phenol from aqueous solutions by adsorption on sewage treatment plant biosolids (BS) as low-cost adsorbent were carried out with an aim to obtain information on treating phenol-containing wastewater from different industries. A series of experiments were undertaken in a batch adsorption technique to access the effect of the process variables i.e. initial phenol concentration, contact time, initial pH and adsorbent dose. The results showed that the adsorption capacity of BS in aqueous solution increased with the decrease in initial concentration and pH, and increase in contact time and dose of adsorbent. The experimental results were fitted by Langmuir and Freundlich isotherms to describe the biosorption processes.
