MODIFIED ACTIVATED CARBON FROM ORANGE PEEL FOR EFFICIENT PHENOL REMOVAL FROM WASTEWATER (2025)

The current work inquired into the modification of Orange Peel Activated Carbon (OPAC) for enhanced dismissal of phenol from wastewater. The Activated Carbons (ACs) were prepared by pyrolysis (OPAC), nitric acid (HNO3 -OPAC), and zinc chloride (ZnCl2 -OPAC) method. The adsorption pattern of ACs was evaluated by FTIR, BET, XRD, SEM, and EDAX studies. ZnCl2 -OPAC, with the highest Brunner Emmet and Teller (BET) surface area (1489 m2 /g) among all was the best for phenol adsorption with maximum eff

Removal of PAHs from Wastewater Using Powdered Activated Carbon: A Case Study (2021)

The aim of this study was to develop immobilized microorganism carrier for effectively degradation of petroleum hydrocarbons (PAHs), especially pyrene. Powdered activated carbon (PAC) was used to immobilize the bacterial consortium (Klebsiella pneumoniae and Pseudomonas aeruginosa) with binder CaCl2 and sodium alginate (SA) for improving mass transfer rate of the pyrene pollutants. Mass transfer properties, embedding ratio, and mechanical strength were inspected for the immobilization particles.

Enhanced phenol removal from wastewater via sulfuric acid activated eggshell derived carbon (2025)

Abstract This research explores the development of an innovative activated carbon adsorbent (ACES) derived from waste eggshells through sulfuric acid activation to effectively remove phenol from simulated wastewater. Optimization of adsorption parameters was conducted using Design-Expert 13 software and response surface methodology (RSM). Under optimal conditions (initial phenol concentration of 25.015 mg/L, adsorbent dosage of 4.913 g/L, pH of 4.693, and temperature of 25.013 °C), ACE

Removal of Phenol From Wastewater by High-Gravity Intensified Heterogeneous Catalytic Ozonation With Activated Carbon (2021)

Abstract In this study, the high-gravity technique is used to intensify the heterogeneous catalytic ozonation with activated carbon (AC) as the catalyst for removal of phenol from wastewater in a rotating packed bed (RPB), and the effects of high-gravity factor, inlet O3 concentration, liquid-gas ratio and initial pH on the degradation and mineralization of phenol at room temperature are investigated. It is revealed that the degradation rate of phenol reaches 100% at 10 min and the remov

Tailoring mesoporous ferrocene-modified activated carbon derived for phenol removal in wastewater (2024)

Abstract This present study investigates the adsorption capacity of synthesized activated carbon/ferrocene composite (AC-H3PO4/Fe7S8) for phenol removal in wastewater. The structural, porosity, and morphology of the synthesized activated carbon/ferrocene composite were determined using FTIR, BET, XRD, and SEM. Parameters varied at different concentrations during the adsorption process include adsorbent dosage, contact time and pH. The AC-H3PO4/Fe7S8 composite achieved 98% removal efficie

Sex Determination and Differentiation (2022)

Abstract The biological sex of a human being is dependent on a genetic pathway starting from the chromosomal set that determines the differentiation of the gonads. In this chapter the current knowledge of the physiological genetic regulation of gonadal development, termed sex determination is described, followed by the endocrine differentiation into the usual phenotypes of male and female. The delicate complexity of these pathways is not only dependent on the genetic composition,

The female (XX) and male (YY) genomes provide insights into the sex determination mechanism in spinach (2020)

Abstract Sexual reproduction is the primary means of reproduction for the vast majority of macroscopic organisms, including almost all animals and plants. Sex chromosomes are predicted to play a central role in sexual dimorphism. Sex determination in spinach is controlled by a pair of sex chromosomes. However, the mechanisms of sex determination in spinach remain poorly understand. Here, we assembled the genomes of both a female (XX) and a male (YY) individual of spinach, and the

Person, Gender, Sex, Sexuality (2023)

A second contemporary Orthodox theological anthropology also suggests a parallel between God and the image of God of God found within humanity. Theological personalism suggests that human persons, like their divine prototype, are essentially unknowable. Like their Trinitarian counterparts, we can describe human persons, at best, in relation to other persons. This fundamental unknowability opens possibilities for each unique, free, and relational human person to act in ways that exceed their inhe
