Banana peel; Chromium; Low-cost; Acrylonitrile; Grafting Abstract The adsorptive removal of hexavalent chromium Cr(VI) from aqueous solutions was investigated by acrylonitrile grafted banana peels (GBPs). Banana peels were treated with 10% HCl, followed by alkaline hydrolysis with 10% NaOH, and washed thoroughly. The bleaching of alkali hydrolyzed peels was carried out with sodium chlorate (NaC...

BACKGROUND Many clinicians have used glycolic acid (GA) peels for facial acne, scarring, and hyperpigmentation, mainly in lighter skin types. Salicylic-mandelic acid combination peels (SMPs) are a newer modality, and there have been no well-controlled studies comparing them with other conventional agents. OBJECTIVE To compare the therapeutic efficacy and tolerability of 35% GA peels and 20% s...

OBJECTIVE To quantitatively examine the effects of skin rejuvenation regimens in treating photodamaged skin. METHODS Fourteen patients with photodamaged skin were considered for analysis. Skin rejuvenation regimens were as follows: (1) 10 weeks of treatment with topical 0.05% tretinoin emollient cream, (2) 10 weeks of treatment with 0.05% tretinoin emollient cream and topical ascorbic acid lo...

OBJECTIVE To evaluate the efficacy of treatment of established acne scars with a sequential combination of treatment using a 1450-nm, midinfrared, nonablative diode laser with dynamic cooling spray and 30% trichloroacetic acid peels. METHODS In this prospective study 9 patients with atrophic rolling, boxcar, or both types of scars received 4 monthly treatments using a 1450-nm, midinfrared, no...

The present study provides an in-depth characterisation of the non-anthocyanin and anthocyanin phenolic compounds potato peels from ten coloured varieties. Furthermore, underexplored bioactive potential (antioxidant, cytotoxic anti-inflammatory capacities) studied is comprehensively analysed. Among phenolics, caffeic a caffeoylquinic acid were found in highest concentrations all samples, which ...

This study aimed to explore the viability of converting potato peel waste into bioethanol using a custom-produced multi-enzyme preparation. Various pretreatment approaches were employed on peels, including thermal, chemical, and thermo-chemical methods. These methods involved boiling for 30 60 min, steaming at different pressures durations, applying concentrations chemicals, H2SO4, HNO3, CH3COO...
