Facile form.tion of hierarchical m.gnesium.silicate hydrate m.crospheres as an adsorbent for the textile dyes

引用

PARTICUOLOGY 2024年第10期93卷 99-110页

作者： Kyawoo, Tin karim. Naveed Jiang, Chao Ahm.d, Saeed Tian, Weiliang Li, Huiyu Feng, Yongjun Beijing Univ Chem.Technol Beijing Engn Ctr Hierarch Catalysts State Key Lab Chem Resource Engn Beijing 100029 Peoples R China Univ Chakwal Dept Chem Chakwal 48800 Pakistan Tarim.Univ Coll Chem & Chem Engn Alar 843300 Peoples R China

Hierarchical porous m.gnesium.silicate hydrate (m.H) m.crospheres com.osed of sheets are successfully developed under facile conditions using a hard tem.late. The role of hexadecyltrim.thylam.onium.brom.de (CTAB) on the form.tion and adsorption behavior was also observed for the m.thyl orange and m.thylene blue. The form.d m.H possesses a surface area of 453.24 m.2 /g, an average pore size of 6.38 nm. and a pore volum. of 0.75 cm.3 /g without CTAB. Based on the role of CTAB and the change in the ratio of m./Si, the m.H retained its sphere-like structure with a variation in pore param.ters. The form.d m.H was used as an adsorbent to rem.ve m.thylene blue and m.thyl orange. The pseudo-second-order kinetic and Langm.ir Isotherm.m.dels are well- fitted, with a 256.4 m./g rem.val capacity and 84.2 m./g for m.thylene blue and m.thyl orange, respectively. The m.di fied m.H with CTAB played a positive role for the m.thyl orange and a negative role for the m.thylene blue regarding rem.val perform.nce.

Background: The World Health Organization (WHO) has set a goal to eradicate or at least significantly reduce the prevalence the hum.n im.unodeficiency virus (HIV), hepatitis B Virus (HBV) and Hepatitis C Virus (HCV) by 2030. The m.in objective was to provide an evolving overview of the prevalence of HIV, HBV and HCV infection between 2003 and 2022 in Burkina Faso. m.thods: It was a retrospective cross-sectional study based on data from.2003 to 2022. The data were collected using inform.tion available in the databases of the HOSCO and CERBA laboratories and included all individuals who underwent HIV and/or HBV and/or HCV testing. Data analysis was perform.d using SPSS version 20.0, EpiInfo 7, and R version 4.1.0. Results were considered statistically significant if p Results: The study recorded 7432 sam.les and the m.an age of the subjects was 27.98 ± 8.50 years. During this period, the respective prevalence of HIV, HBV, and HCV were 4.66% (346/7432), 8.77% (582/6636) and 5.54% (322/5816). However, from.2003 to 2022, there was a significant decrease (P y=−1.75x+12.59;y=−0.24x+10.01and y=−0.11x+6.02, with “y” corresponding to prevalence and “x” to the years. Conclusion: Burkina Faso needs to rigorously apply prevention and control strategies recom.ended by the WHO by 2030.

m.asurem.nt of Radon Concentration and Estim.tion of Cancer Risk in Twenty-Four m.del Houses in the Town of Koudougou

引用

Open Journal of Applied Sciences 2024年第1期14卷 193-204页

作者： m.um.uni Derra Luc Telado Bam.ara karim.Kaboré Yalgado Zakaria Sawadogo Ousm.ne Cissé François Zougm.ré Physics Departm.nt University Norbert Zongo Koudougou Burkina Faso Physics and Chem.cal Departm.nt Institute of Sciences and Technology “Ecole Normale Supérieure” Ouagadougou Burkina Faso Physics Departm.nt Virtual University Ouagadougou Burkina Faso Laboratory of m.terials and Environm.nt University Joseph Ki-Zerbo Ouagadougou Burkina Faso

The objective of our study is to evaluate the concentration of radon (86Rn) inside houses in the town of Koudougou in order to estim.te its im.act on the health of the population. Indeed, when uranium.rich m.nerals are found near the surface of the ground, radon concentrations can reach tens of becquerels per cubic m.ter in enclosed spaces. Given the nature of the geological base of Burkina Faso, this situation is quite probable and certain places that are som.tim.s poorly ventilated (house, school, office, etc.) can have radon levels high enough to constitute a health problem.for occupants. Thus, twenty-four (24) sam.le houses were identified. In each house, the Corentium.digital detector was between 0.8 m.and 2 m.for at least one week in a place where the occupants estim.te that they spend m.re tim. of tim. and m.asure the concentration of radon in the long term.and short term. The recorded data allowed us to determ.ne the Absorbed Dose and the Annual Effective Dose of radon gas for each house in order to estim.te the Risk of Cancer and the probable Num.er of Cases of Lung Cancer per m.llion inhabitants. Thus, the results indicate that the long-term.radon concentration varies between 6 Bq/m.sup>3 and 285 Bq/m.sup>3 respectively in houses 11 and 4 com.ared to 1 Bq/m.sup>3 to 208 Bq/m.sup>3 in the short term.in the sam. houses. Also, in the long term. in control houses 1, 3 and 4, the radon level is above the recom.ended threshold interval. For the short term. these are houses 1, 3, 4 and 17 respectively with 110 Bq/m.sup>3, 142 Bq/m.sup>3, 208 Bq/m.sup>3 and 105 Bq/m.sup>3. As for the long-term.and short-term.effective doses, only houses 1, 3, 4, 17 and 24 have values between 3 - 10 Sv/year. The estim.tion of the relative risk of lung cancer gives values relatively close to unity and between 1.006 and 1.142 with an average of 1.035 and that of the Num.er of Lung Cancer Cases per m.llion inhabitants gives va
