Introduction: As the most hazardous sewage, hospital wastewater contains various contaminants, and its uncontrolled discharge can seriously damage the environment. Bandar Abbas is located in an arid and semi-arid region therefore, hospital wastewater should be treated through an appropriate and economic method. This study aimed to determine the efficiency of electrocoagulation with aluminum and...

Aluminium is widely used in medicines, as food additives, as water purification agent, as in the making of household cookware and storage utensils. Aluminium can get into the human beings via digestive tract or via lungs or through parenteral route. Absorption of aluminium depends upon the chemical forms of aluminium taken up and pH values in GIT. In acidic medium, absorption becomes higher. Al...

Background & Aims of the Study: Coagulation is an essential process for the removal of fine particulate matter in water treatment. Polyaluminium ferric chloride (PAFC) is a composite inorganic polymer of Aluminium and ferric salt. This study was conducted to find out the optimum coagulation conditions for the removal of turbidity, color and organic matter (UV absorbance) in low to mediu...

Electrochemical methods and processes have been applied for many years in environmental applications such as water/wastewater treatment, recovery of metals, electroplating and qualitative/quantitative analysis in various aqueous media. Among these processes, electro‐ coagulation (EC) has gained many interest due to providing simple, reliable and cost effective operation for the treatment of was...

An RP-HPLC method for the separation and determination of aluminium(III), vanadium(V), iron(III), copper(II) and nickel(II) with CALKS (Chromazol KS) and PAR ([4-(2-pyridylazo)resorcinol]) chelating on a YWG-ODS column was developed. A mixture of methanol-tetrahydrofuran(THF)-water (60:5:35 v/v) containing 0.2 mol/L LiCl, 5 x 10(-5) mol/L CALKS, 5 x 10(-5) mol/L PAR and acetate buffer solution ...

Contaminated groundwater resulting from pyrite oxidation of acid sulphate soils (ASS) is a major environmental problem in coastal Australia. A column test was carried out for an extended period with recycled concrete to study the efficiency of the reactive materials for neutralising acidic groundwater. Results show that the actual acid neutralisation capacity of the recycled concrete could decr...
