A comparative study of Zinc (II) ions removal by a locally produced Granular activated carbon

Physiochemical properties of wastewater effluent from the plants of a brewery in Lagos, Nigeria were analyzed. The adsorption capacity of Granular activated carbon from animal horns when compared with the available commercial Granulated Activated Carbon (GAC) has been presented. Kinetics of adsorption was also investigated. The adsorption isotherms could be well defined with Freundlich model instead of Langmuir model for both GAC studied. The experimental data, when applied to the first and second-order kinetic models, followed the first-order with r² = 0.931 for GAC from animal horns while commercial GAC followed the second-order with r² = 0.936. The results illustrated how animal horns, a solid waste disposal menace from the abattoir at the Oshodi market in Lagos metropolis, was used as an effective biosorbent for the removal of Zn 2+ ions; offering a cheap option for primary treatment of the wastewater effluent

Empirical Model for Predicting Rate of Biogas Production

Rate of biogas production using cow manure as substrate was monitored in two laboratory scale batch reactors (13 liter and 108 liter capacities). Two empirical models based on the Gompertz and the modified logistic equations were used to fit the experimental data based on non-linear regression analysis using Solver tool in Microsoft Excel. The 13-liter reactor was used in Experiments1 & 2 and in Experiment 3 the 108-liter reactor was used. In all the three experiments, Gompertz model gave a better goodness of fit than the modified Logistic model. The cross correlation coefficients for experiment 3 are 0.9972 and 0.9965 for Gompertz and Modified Logistic models respectively. Atomic absorption spectroscopy (AAS) analysis of the biogas indicates that its methane content is above 70% in both reactors.Keywords: Empirical model, Non-linear regression, biogas production, cow manure

Perspective of Undergraduate Students of University in Edo State on the Side Effect of Food Additive on Human Health

This study examined the perspectives of undergraduate students on the side effects of food Additives to human health. Two research questions were raised to guide the study. The population of this study comprised of all undergraduates students in Edo State. The study adopted the descriptive design. The sample size for this study comprised one hundred undergraduate  students in Ambrose Alli University  Ekpoma, Edo state, Nigeria.  using random sampling techniques.  Questionnaire was used to collect data for this study, the questionnaire was made up of two parts, section A and B, section A contains demographic information of the respondents, section B contains research area of investigation, the instrument was validated by experts in Home Economics Education, department of vocational and technical education, AAU. Split half method was used to obtain reliability coefficient of  0.76 . The researcher personally administered the copies of the questionnaires to the respondents. It contains twenty items. The questionnaires were collected immediately to avoid loss of data’s. The findings of this study revealed that most undergraduate students are not aware of side effect of food additives  to human health, it was also revealed that the respondents consumed some harmful additives in large quantity, which is dangerous to  human health,  it was recommended among others that Government should create awareness  on the side effect of food additive to human health. The public should avoid harmful food additives and reduce consumption of processed food. Keywords:Food Additives, Types of Food Additives, Effects  of Food Additives, Undergraduate Students.

An Assessment on Awareness and Acceptability of Child Adoption in Edo State

The study examines the awareness and acceptability of child adoption in Edo State. The design used for the study was survey design. The population for the study is made up of adults male and female in Esan West Local Government Area. One hundred respondents were randomly selected using random sampling techniques. The validity was ascertained by experts Reliability was established using the split – half method. Coefficient reliability of 0.75 was obtained. The instrument used for data collection was a questionnaire with twenty items. The data was analyzed using simple percentages according to the research questions formulated. The results of this study revealed amongst others that there is awareness and acceptability of child adoption. But, Large percentage of respondents disagreed with the fact that adopted children should have equal right to properties as biological children.  It was therefore recommended that pregnancies that are not planned for especially from teenagers should not be aborted, childless couples should be free to adopt child or children Keywords: Child Adoption, family, childlessness, barren, marital, childre

Application of adsorbent as a novel technique during biodegradation of a polycyclic aromatic hydrocarbon (anthracene)

The use of an alternative technique as a management strategy for the decontamination of hydrocarbonbased pollution in soil has been advanced in this work. The study investigated the degradation ofanthracene, a three-ringed benzene derivative, in clay soil at ambient conditions under the influence of hydrophilic compound (carbon), thermally activated at temperatures of 300, 500, 700 and 900oC. Thesoil (500 g) was impacted with 1:1 of the contaminant anthracene and activated carbon from groundnut shell in a water medium at a flow rate of 5.0 ml/min. Experimental results revealed that there was asignificant reduction in the level of anthracene in the soil matrix with time. The percentage reduction was found to be directly dependent on the activation temperature. The estimated reaction rate constantwas found to be 0.014/h (control sample without activated carbon) while for the experimental samples, the values ranged from 0.018 - 0.051/h. The study therefore affirms that the presence of activatedcarbon in microbial degradation of anthracene, elicits an enhanced disappearance rate of the hydrocarbon
