Oil Water

The wastewater produced by the metal industry is often present in the form of oil-in-water (O/W) or water-in- oil (W/O) emulsions. These fluids contain a certain amount of valuable oil that can be recovered in the recycling process. Therefore, the development of novel, efficient, and low cost processes for the treatment of metalworking fluid is necessary. Demulsification to separate oil/water mixtures is a very interesting option because it allows the recovery and reuse of the lubricant oil and effects in cleaner, easily treatablemwastewater.Chemical destabilization is the most common way of demulsification of metalworking fluids. As an example, inorganic salts can be used as demulsifiers. In the presented work the efficiency of treatment of cutting emulsions with chemical demulsification with usage of aluminum sulfate (IV) is described. The emulsion was prepared with Emulgol-ES12 self-emulsyfing oil delivered by Orlen S.A. In the research the feasibility of the demulsifier was checked.The novel in this paper is determination of the optimal dosage of emulsifier using the TurbiscanLab® apparatus. It is relatively quick and precise method that can be applied in the industry.

Neonatal Conjunctivitis

Neonatal conjunctivitis is a worldwide problem.  Although global incidence is not known, incidents of 1-24% have been reported from various regions of the world especially those practicing home delivery without standard prophylaxis.  This study was an in-vitro investigation on possible prophylaxis for ophthalmia neonatorum (ON) like potassium aluminum sulfate (KAlSO4)2 and povidone iodine (C6H9I2NO) in comparison to tetracycline. A five by three (5x3) factorial experiment in Completely Randomized Design (CRD) was used in this study.  Factor A was the five-test bacteria, namely Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae, Enterobacter spp. and Pseudomonas spp. while Factor B was the experimental variables or the substances to be tested such as alum, povidone iodine and tetracycline.  Aluminum was diluted and subjected to purity test prior to bacteria assay.  The zone of inhibition was measured using a caliper and results were recorded.  Based on the in-vitro analysis, aluminum showed a positive response to the five tested bacteria as it yielded a comparative mean results of growth inhibition.   Among the possible applications of the findings in the study could be the formulation of antiseptic eye drops with the use of alum or Povidone iodine to be used as prophylaxis to guard against neonatal conjunctivitis.

Color Depth

Tea polyphenol (TP) was used to dye silk by the post-mordanting method using three different metal salts as the mordant; ferrous sulfate, copper sulfate and potassium aluminum sulfate. The results were analyzed in terms of color strength (K/S value) and fastness characteristics as well as the influence of variables such as dyeing time, temperature and pH on the color depth of the dyed sample. A weak acid medium and a low dyeing temperature were found to be optimal for adsorption of TP when dyeing silk with TP. Comparing the color shade of dyed silk obtained with different metal salts as the mordant showed that ferrous sulfate gave the highest K/S value followed by copper and then aluminum. During the soaping colorfastness test, a relatively large color change was associated with increased color strength as well as non-staining of adjacent fibers.
