The use of rare earth elements is a growing trend in diverse industrial activities, leading to the need for eco-friendly approaches their efficient recovery and reuse. aim this work development an environmentally friendly competitive technology those from wastewater. Kinetic equilibria batch assays were performed with zeolite, without bacterial biofilm, entrap ions aqueous solution. Continuous also column setups. Over 90% removal lanthanum cerium was achieved using zeolite as sorbent,...
Abstract Objectives This study aimed to improve the performance and mode of administration a glass-reinforced hydroxyapatite synthetic bone substitute, Bonelike by Biosckin® (BL®), association with dextrin-based hydrogel, DEXGEL, achieve an injectable moldable device named DEXGEL Bone. Methods Twelve participants requiring pre-molar tooth extraction implant placement were enrolled in this study. BL® granules (250–500 µm) administered 6 randomized whereas other received After months, biopsy...
The purpose of this paper is to present some results an ongoing project that intends improve internal logistics visibility using RFID at electronics company the automotive sector. first step was identify traceability problems raw materials and design RFID–based solution solve such problems. Additionally, main challenges related implementation were identified discussed. Through interviews, documental analysis, observation, current logistic processes are described identified. This is, mainly,...
Several chemicals, such as pesticides and heavy metals, are frequently encountered together in environment matrices, becoming a priority concerning the prevention of their emissions, well removal from environment. In this sense, work aimed to evaluate effectiveness permeable biosorbent bio-barrier reactor (PBR) on atrazine metals (copper zinc) aqueous solutions. The was built with bacterial biofilm R. viscosum supported 13X zeolite. One aims is investigation toxic effects atrazine, copper...
Abstract Y‐encapsulated Cu II –purine complexes were synthesized, characterized and studied in the catalytic oxidation of cyclohexene. Encapsulation was achieved by ion‐exchanging complex from aqueous solutions containing both purine ligand, 9‐methyl‐6‐(methylamino)purine, copper, different pH, with a purine/Cu molar ratio 5:1. The resulting materials surface analysis (XPS, SEM XRD), chemical analysis, spectroscopic methods (EPR, FTIR UV/Vis) thermal (TGA), which indicated that effectively...
The toxic effects of diethylketone (DEK) in aqueous solution with different concentrations Al3+, Cd2+, Ni2+ and Mn2+ were evaluated at lab-scale. It was established that Streptococcus equisimilis is able to efficiently remove DEK heavy metals. proved this joint-system has excellent capacity biodegrade high the presence Mn2+. With exception uptake for all metals increased as initial concentration each metal mixed increased. breakthrough curves are best described by Adams Bohart model Yoon...
Two contaminating fungi were isolated from a bioreactor containing diethylketone and Streptococcus equisimilis, subsequently characterized at molecular level identified as belonging to the Alternaria Penicillium genera. The ability of these biodegrade DEK is evaluated. kinetic parameters are estimated using four growth models for biodegradation organic compounds available in literature. experimental data sp. was found be better fitted by Haldane Luong respectively. Biodegradation rate...
The effect of pH on the sorption capacity vermiculite towards cadmium and nickel was tested in batch systems it shown that percentages increase with an mass initial pH. Maximum were obtained for a 8 4 g (86.5% Cd2+ 86.1% Ni2+, solutions 100 mg/L metal). As consequence, possible to establish range optimal biosorption processes, by combining so determined growth Streptococcus equisimilis, bacterium used treat contaminated water. Pilot-scale experiments S. equisimilis biofilm supported...
