Iron handicraft is one of industries that process iron ore into handicraft products and produce lathe waste. Iron lathe contains 96.08% iron metal which is potential source as a precursor for synthesis of goethite pigment. The method used for synthesis wa... see more

Lathe waste contains high iron content potential to be further processed into goethite pigment. The purpose of the research was to determine the effect of synthesis temperature on the structure, colour values, and morphology of goethite pigment. The synth... see more

The elimination of metal waste generated during the initial manufacturing processes of industrial plants and workshop machines still a big problem.  The current investigation dealt with adding the metal wastes produced by machinery processing such as... see more

The aim of the research is to improve the technological scheme of treatment of iron-containing wastewater from etching operations by creating combined systems, including reagent wastewater treatment, their mutual neutralization, regeneration of etching so... see more

This paper reports about the use of recycled iron powder (IP) in producing cement mortar under normal conditions. Flow table test was performed on fresh mortar. Destructive tests were conducted on cubes of the hardened mortar to obtain the compressive and... see more

The technologies for extracting an iron-containing catalyst from process streams of direct chlorination of ethylene, as well as methods for the disposal of organochlorine wastes from vinyl chloride production, are considered. Problems arising from thermal... see more

Atom absorption spectrophotometer (AAS) had been used to analyzed Ferro in the soil and in the green mustardleaf (Brassica junjea) treated with phenolics extract from the agricultural wastes of clove leaf (Eugenia aromatica),rice straw (Oryza sativa) and ... see more

Methylene blue is one of the dyes in textile industries which has a negative impact on the environment. This compound is very stable, so it is difficult to degrade naturally. Methylene blue can be harmful to the environment if it is in a very large concen... see more

The reduction of copper concentration in the electroplating industry wastewater by electrodeposition method by means of Atomic Absorption Spectrophotometer (AAS). The result of research showed that degradation and is big of elimination percent of copper m... see more
