Calcined sugar scum as a low-cost adsorbent for dye removal from aqueous solution: Equilibrium, kinetic and modeling
Solid Waste Management
Batch adsorption experiments have been conducted to investigate the adsorption properties of the calcined sugar scum powder for methylene blue (MB) and methyl orange (MO) as models for cationic and anionic dyes. The kinetic and equilibrium adsorption have been investigated to determine the...
Synthesis of pyrene-based Fe(II)-complex and its photovoltaic properties
General
(E)-2-((pyren-1-ylmethylene)amino)phenol (3) containing pyrene linked through an imine bond to a phenol unit was synthesized and its Fe-complex 4 was prepared. The complex 4 is characterized by infrared (IR), x-ray diffraction (XRD) and UV-Vis spectroscopy techniques. The synthesized complex was...
An assessment of microclimatic conditions inside vegetated and non-vegetated small-scale open spaces in the Athens urban environment
Climate change mitigation and adaptation
This study is aimed at quantifying the contribution of small urban green spaces to mitigate adverse bioclimatic conditions within the urban environment of Athens during summer and investigate their thermal profile during a warm, a cold and a transitional period. Six green and non-green sites inside...
Optimization of ACH Coagulant, Settling Time and Powdered Activated Carbon as Coagulant Aid with Economic Analysis
Water and Wastewater Treatment
Regular water treatment-plant (WTP) comprises of a number of units. Of course, problems exist throughout design and operation of the WTP units. Consequently, the current re-search aimed to minimize the shortcomings of the coagulation, sedimentation, and the adsorption methods through applying...
Utilization and uncertainties of satellite precipitation data in flash flood hydrological analysis in ungauged watersheds
Floods, Droughts and Water scarcity
Aim of the study is to examine the potential utilization of satellite precipitation data to estimate the peak discharges of flash floods in ungauged Mediterranean watersheds. Cumulative precipitation heights from local rain gauge and the GPM-IMERG were correlated in a scatter plot. The calculated...
Poly(4-vinylphenol) coated magnetic nanoparticles based dispersive solid-phase microextraction of the determination of mercury(II) in water
Innovative environmental solutions
The development of magnetic sorbent for dispersive solid-phase micro-extraction (DmSPE) often requires lengthy multi-step reactions. This research revealed a simplified method for preparing magnetic sorbent for the DmSPE using poly(4-vinylphenol) (PVP). The magnetic sorbent (PVP@MNP) was prepared by...
Organic pollutants removal from oilfield produced water using nano magnetite as adsorbent
Water and Wastewater Treatment
The current study investigates the ability of Nano magnetite as an adsorbent to remove organic materials from oilfield-produced water (PW). The effect of several variables on the removal procedure was investigated, such as nano magnetite dose, pH of solution and adsorption period. The adsorbent was...
Integrated system for paclitaxel production from endophytic fungus, Neopestalotiopsis clavispora ASU1 and subsequent extraction of chitosan from fungal biomass wastes
Biowaste
Nowadays, breast cancer is considered to be one of the most prevalent diseases worldwide, this initiated interest and growing demand for taxol production in large quantities. The limited availability of traditional taxol production from the Pacific yew trees has encouraged research into the...
ECO-FRIENDLY DYEING OF COTTON FABRIC WITH WASTE TEA LEAVES BASED TANNIN NATURAL DYE
General
Natural products have always been appreciated due to the awareness about environmental standards for global health by using green technologies in their isolation and extraction. Thereupon natural dyes have been used in all fields due to having ecofriendly, therapeutic and aesthetic nature. For the...
Use of phytoremediation for pollution removal of hexavalent chromium-contaminated acid agricultural soils
Soil and groundwater contamination and remediation
Chromium is a common heavy metal pollutant found in industrial wastewaters which may pollute agricultural soils through groundwater and watering. Phytoremediation is an economical and highly applicable method for removal of pollutants from agricultural soils. This research was carried out for the...
