the main purpose of this research is to evaluate the hydrochemical properties, con-trolling processes and metal concentrations in kaka-reza river water (lorestan province). to this end, 15 water samples were collected and physicochemical prop-erties (ph-ec), cation-anion contents along with concentrations of some heavy metals were determined using the standard analytical methods. the results re...

The removal of copper (II) ion by using ultrasound pre-treatment to increase the pores structure and surface area on peanut husk powder via direct sonication (ultrasound probe) and indirect ultrasound (ultrasound bath) at powder level 3.5 W. In previous studies, researchers had applied ultrasound simultaneous with adsorption process. This method is not suitable to treat huge amount of heavy met...

the hazardous effect of heavy metals on the histopathology of selected organs of the freshwater fish common carp (cyprinus carpio l.) was investigated. gill, liver, kidney and flesh samples were collected after 32 days of exposure to a sublethal concentration of 5 mg/l of combined (cd + pb + cr + ni) metal solution containing 1.25 mg/l of each metal ion (1/10th of lc50 / 48h) was analyzed by us...

background: evaluation on the toxicity of two mainly contaminant heavy metals, cadmium (cd) and lead (pb) through the food chain was the aim of this study. methods: a total number of 270 healthy common carp (4±1.14 g) in april, 2015 transported to the khatam alanbia university of technology, behbahan, iran. fishes were divided into three groups and transferred to the 20 l aquaria each containin...

This paper reports new insights on the role of the inorganic composition of Bone char (BC) on its sorption properties for the removal of heavy metals Cd, Ni, and Zn ions from aqueous solution. In particular, we showed the importance of both composition and surface chemistry of BC on its sorption properties for the removal of these metal ions in aqueous solution. Results of physicochemical chara...
