Recent advances in the treatment of PAHs in the environment: Application of nanomaterial-based technologies
(
Elsevier B.V.
, 2022 , Article)
Polycyclic aromatic hydrocarbons (PAHs) are one of the most frequent petroleum hydrocarbons detected in the environment. PAHs are receiving global attention due to their toxicity, environmental persistence, and potential ...
Selective removal of dibenzothiophene from commercial diesel using manganese dioxide-modified activated carbon: A kinetic study
(
Taylor and Francis Ltd.
, 2015 , Article)
With a total concentration of 7055 mgS/kgfuel, the content of organosulphur compounds (OSCs) in local diesel is 20 times higher than the regulated value. Analysis revealed that 30% of OSC is originated from dibenzothiophene ...
Investigating the effect of temperature on calcium sulfate scaling of reverse osmosis membranes using FTIR, SEM-EDX and multivariate analysis
(
Elsevier B.V.
, 2020 , Article)
Membrane fouling is one of the major hurdles in widespread use of seawater reverse osmosis (SWRO) in desalination industry. There are various factors that affect the inorganic fouling or scaling of Reverse osmosis (RO) ...
Multivariate analysis for FTIR in understanding treatment of used cooking oil using activated carbon prepared from olive stone
(
Public Library of Science
, 2020 , Article)
In this study, activated carbons prepared from the green and black olive stone (green OSAC and black OSAC) were used as adsorbents to investigate their removal efficiencies for oxidation products and polar compounds from ...

(
Elsevier B.V.
, 2020 , Article)
The presence and fate of polyaromatic hydrocarbons (PAHs) in the environment are receiving a great concern. In this study, three oil-contaminated soils (industrial area, Dukhan city, and artificial soils) were utilized to ...
Novel bioadsorbents based on date pits for organophosphorus pesticide remediation from water
(
Elsevier Ltd
, 2020 , Article)
The aim of the study was to examine the efficiency of date pits as an adsorbent to remove the organophosphate pesticide (profenofos) from water. A thermodynamic study was carried out to determine the homogeneity and ...

(
Elsevier Ltd
, 2020 , Article)
Membrane fouling affects the performance of membrane technologies such as reverse osmosis (RO), in water treatments and desalination industries. The membrane fouling is a multifaceted phenomenon and various components of ...
Influence of diesel acidification on dibenzothiophene removal: A new desulfurization practice
(
Elsevier
, 2015 , Article)
Commercial diesel is often loaded with organosulphur compounds including hard-to-remove dibenzothiophene DBT and other derivatives. Following uncommon and simple procedure, dibenzothiophene was selectively removed upon ...
Introduction to the cyanobacteria
