Contaminated irrigation water can increase trace heavy metals concentration in agricultural soil. The present research aimed to investigate the effect of three types sources, including treated wastewater effluent, Gharasoo river water, and well with chemical fertilizer, on accumulation ecological risk soils. Soil samples were collected before after crop evaluate metal concentrations. analyzed determine presence arsenic, nickel, cadmium, iron, chromium, zinc, lead, copper, manganese. Based...
Abstract BACKGROUND In the present work, Hg ( II ) is considered as one of most dangerous elements being released excessively into environment from various sources. Therefore, aim this study removal wastewater effluent by synthesizing a magnetic chitosan modified with glutaraldehyde MCS‐GA an adsorbent. The composite structure was characterized using SEM / EDAX , FTIR and XRD techniques. adsorbent tested batch system to determine optimum conditions for removing under real conditions. RESULTS...
Abstract This research was conducted to study the adsorption of ammonium ions onto pumice as a natural and low-cost adsorbent. The physico-chemical properties granular were characterized by X-ray diffraction (XRD), Fourier transforms infrared spectroscopy (FTIR) scanning electron microscopy (SEM). Modeling optimization NH 4 + sorption process accomplished varying four independent parameters (pumice dosage, initial ion concentration, mixing rate contact time) using central composite design...
This study investigated the adsorption capacity of Remazol Black B (RBB) from aqueous solutions using a pumice stone as cheap, high-frequent, and available adsorbent. The raw was modified five acids: Acetic, Sulfuric, Phosphoric, Nitric, Hydrochloric acid. Fourier transform infrared spectrograph (FTIR), x-ray fluorescence (XRF), scanning electron microscopy (SEM) were used to analyze morphological chemical properties adsorbents. equilibrium Langmuir, Freundlich, Temkin, Dubinin -...
Levels of some essential and toxic heavy metals such as lead, cadmium, chromium, nickel, zinc copper in cereals agricultural products obtained from the markets Kermanshah city, west Iran, were determined by inductively coupled plasma-optical emission spectrometry (ICP-OES). The average concentrations for lead cadmium higher than maximum levels set Codex Alimentarius. A potential human health risk assessment was conducted calculating estimated weekly intake (EWI) eating comparison these...
Phthalic acid esters, including diethyl phthalate (DEP), which are considered as top-priority and hazardous pollutants, have received significant attention over the last decades. It is vital for industries to select best treatment technology, especially when DEP concentration in wastewater high. Meanwhile, anaerobic biofilm-based reactors a promising option. Therefore, present study, biological removal of from synthetic wastewater, two different reactors, fixed film baffled reactor (AnFFBR)...
Malathion is a persistent organophosphorous insecticide, which widely used in industry, agriculture, and public health. The characterization of Magnetic Graphene Oxide (MGO) was determined by scanning electron microscopy, transmission X-ray diffraction, Fourier transform infrared spectroscopy, energy dispersive X-ray, vibrating sample magnetometer, zeta potential. performance the adsorbent removing malathion evaluated different operational conditions including pH, contact time, dosage,...
The aim of this study is to evaluate central composite design (CCD) and the Taguchi technique in adsorption process. Contact time, initial concentration, pH were selected as variables, removal efficiency Pb was chosen for designated response. In addition, face-centered CCD L9 orthogonal array used experimental design. result indicated that, at optimum conditions, 80%. However, value R2 greater than 0.95 both techniques, which revealed that techniques suitable conformity with each other....
Abstract Emerging and hazardous environmental pollutants like phthalic acid esters (PAEs) are one of the recent concerns worldwide. PAEs considered to have diverse endocrine disrupting effects on human health. Industrial wastewater has been reported as an important environment with high concentrations PAEs. In present study, four short-chain including diallyl phthalate (DAP), diethyl (DEP), dimethyl (DMP), (PA) were selected a substrate for anaerobic fixed film bed reactor (AnFFFBR). The...
