Data on characterization, model, and adsorption rate of banana peel activated carbon (Musa Acuminata) for adsorbents of various heavy metals (Mn, Pb, Zn, Fe)

ABSTRACT: This research contains data on the adsorption test and characterization of banana peel activated carbon as an adsorbent for water contaminated with various heavy metals. Banana peel is a common post-harvest waste, making it easy to obtain. Atomic Absorption Spectroscopy (AAS) is used to investigate the various heavy metal content in polluted water that are harmful to health, such as Mn, Fe, Zn, and Pb in concentrations of 1.351; 1.210; 17.403; and 0.210 mg/L, respectively. These metals exceed the standard limits for clean water quality that are suitable for sanitation hygiene purposes. Banana peel activated carbon samples were tested in polluted water and re-examined using AAS. The parameters used to calculate the percent adsorption of the four heavy metals were variations in adsorbent mass (0.5; 1.0; 1.5; 2.0 g), stirring speed (50; 100; 150; 200; 250 rpm), pH (4; 5; 6; 7; 8; and contact time (30; 60; 90; 120; 150 min). Scanning Electron Microscopy/X-Ray Spectroscopy Energy Dispersion (SEM/EDS) and X-Ray Diffraction (XRD) were used to characterize and determine the morphology, material content, and crystal structure formed by the samples. Brunaurer, Emmet, and Teller/Barret, Joyner, and Halenda (BET/BJH) were used to investigate the surface area, pore size, and isotherm type. This dataset is publicly available for researchers to optimize the potential of banana peel activated carbon as an adsorbent of heavy metals (Mn, Pb, Zn, Fe) in the industrial sector.

Project description:BackgroundBananas and plantains (Musa spp.) are grown in more than a hundred tropical and subtropical countries and provide staple food for hundreds of millions of people. They are seed-sterile crops propagated clonally and this makes them vulnerable to a rapid spread of devastating diseases and at the same time hampers breeding improved cultivars. Although the socio-economic importance of bananas and plantains cannot be overestimated, they remain outside the focus of major research programs. This slows down the study of nuclear genome and the development of molecular tools to facilitate banana improvement.ResultsIn this work, we report on the first thorough characterization of the repeat component of the banana (M. acuminata cv. 'Calcutta 4') genome. Analysis of almost 100 Mb of sequence data (0.15× genome coverage) permitted partial sequence reconstruction and characterization of repetitive DNA, making up about 30% of the genome. The results showed that the banana repeats are predominantly made of various types of Ty1/copia and Ty3/gypsy retroelements representing 16 and 7% of the genome respectively. On the other hand, DNA transposons were found to be rare. In addition to new families of transposable elements, two new satellite repeats were discovered and found useful as cytogenetic markers. To help in banana sequence annotation, a specific Musa repeat database was created, and its utility was demonstrated by analyzing the repeat composition of 62 genomic BAC clones.ConclusionA low-depth 454 sequencing of banana nuclear genome provided the largest amount of DNA sequence data available until now for Musa and permitted reconstruction of most of the major types of DNA repeats. The information obtained in this study improves the knowledge of the long-range organization of banana chromosomes, and provides sequence resources needed for repeat masking and annotation during the Musa genome sequencing project. It also provides sequence data for isolation of DNA markers to be used in genetic diversity studies and in marker-assisted selection.
