Fundamental Islamic perspective of work ethics

Abstract: Purpose – This paper debates the Islamic perspective on the work ethics employed in an organization. It aims to discuss the issues of assumptions involving the Islamic Work Ethic (IWE). Therefore, this paper addresses the gap in the management literature and suggests a group of dimensions from fundamentals of Islam. Design/methodology/approach – The paper reviews the foundations of IWE and investigates various empirical studies conducted in several countries. Then, briefly presents a short historical and conceptual review of the work ethic construct, suggests a general conceptual definition of work ethic, and offers multidimensional model including a series of constructs which can enable researchers to evaluate and measure work ethic in Islamic societies. Findings – The study reveals that there is an evidence of ethics formulation depending on Islamic literature which constructs Islamic values for work. This paper proposes new perspective about the right ethics of work in Islam. Further, multidimensional model including 18 dimensions has been developed to evaluate work ethic in Islamic societies. Research limitations/implications – This field needs to reconsider the constructs of IWEs where it is far from reflecting Islamic theory. This paper presents new dimensions which can be utilized to enrich this area. Originality/value – This is one of the few attempts to suggest the appropriate constructs of IWE in the management literature. It provides 18 elements responsible and have the promise to strengthen individual transparency and morally which eventually enhance economic progress in Islamic world.

Efficient arsenic(V) removal from contaminated water using natural clay and clay composite adsorbents

Abstract: The natural clay is an abundant, accessible, and low-cost material that has the potential for use in the water and wastewater industry. In this paper, Iranian natural clay and clay/Fe-Mn composite were used to remove toxic arsenic from the liquid environment. The natural clay and clay/Fe-Mn composite were characterized by scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FTIR), energy-dispersive X-ray (EDX), X-ray diffractometry (XRD), thermo-gravimetric analysis (TGA), and atomic force microscopy (AFM) techniques. The effects of parameters (initial pH, temperature, sorption dose, and contact time) on the efficiency and behavior of the arsenic(V) adsorption process were studied. Freundlich (R2 = 0.945 and 0.989), Langmuir (R2 = 0.922 and 0.931), modified Langmuir (R2 = 0.921 and 0.929), and Dubinin-Radushkevich (R2 = 0.706 and 0.723) models were fitted to evaluate the equilibrium data of arsenic(V) adsorption process by natural clay and clay/Fe-Mn composite, respectively. The Langmuir adsorption capacity of arsenic(V) by the natural clay and clay/Fe-Mn composite was determined to be 86.86 mg/g and 120.70 mg/g, respectively. The arsenic(V) adsorption process followed the pseudo-second-order model. Negative values of ΔG° and ΔH° showed that the arsenic(V) sorption by the studied materials is thermodynamically spontaneous and exothermic. According to the findings, the natural clay and clay/Fe-Mn are suitable and recyclable sorbents for arsenic(V) adsorption from aqueous solutions. Also, the composite of clay with iron and manganese can improve the efficiency of clay in the removal of arsenic.
