Chemisrty

The composer Marzena Majcher and singer Małgorzata Kubala (soprano) try to answer the question: how does the Chemistry of Love sounds? through analysis and interpretation of two parts of the composition - I Dopamine and II Phenylethylamine by Marzena Majcher. The concept of the work is based on formulas of chemical substances responsible for the state of falling in love. The analysis presents how the composer transformed the “sum” and “structural” formulas of these substances into the language of music. In interpretation they describe the emotional side of the composition and expression created in the piece. Also they mention the form and composing techniques in the Chemistry of Love, which oscillates at the borderline of music and chemistry.

Malachite dye is among the millions of dyes used in every aspect of our daily life. The adsorption kinetic the pollutant (dye) from adsobate using palm kernel shell (Elaeis Guineasis) as the biomass was studied. From the several experimental parameters measured, the optimum adsorption occurred at 20 minutes giving 92.3%. Adsorption also decreased from 92.49% to 87.9% with increase in absorbent dosage giving the optimum dosage of 2g. Also increase in temperature decreased the adsorption from 95.6% to 92.7% having it optimum temperature to be 30 o C. Increase in dye ion concentration from 10-50mg/L also increased adsorption from 79.3% to 93.0%. There was a decrease in the percentage of dye removed for all the parameters investigated except for dye ion concentration. The value of S F for Langmuir model is 0.232 and R 2 value is 0.6326 while for Freundlich model, the value of 1/n is 2.8092 and R 2 value is 0.9135 which indicate that Langmuir and Freundlich model are both good isotherm models because they have a S F value of < 1 and 1/n value > 1. Pseudo second order model best fit the experimental data than pseudo first order having R 2 values of 1 and 0.5613. This shows that palm kernel shell can be used as an effective biomass for removing waste water from dye.
