Hydrogen Peroxide is marketed in the form of an aqueous solution and being a limiting reagent in this research, its concentration was first determined by titration with standard solution of Potassium Permanganate (0.02M) before its subsequent utilization. The effect of varying mass of CrO3 on the decomposition of fixed volume of H2O2 was studied by measuring the volume of oxygen evolved and the time taken for the evolution to cease. Similarly, the effect of the decomposition of varying volumes of H2O2 with fixed mass of CrO3 was also studied. At the end of the reaction, the volume of O2 evolved and the time taken for the evolution of O2 were equally recorded. The results of the above decompositions indicated that CrO3 acted as a catalyst. The decomposition of H2O2 catalyzed by CrO3 was found to be a first order reaction. This was determined through the measurement of the half-life of the same reaction. The results of the titrations of acidified solution of H2O2 against KMnO4 solution at different time intervals carried out at 35 o C and 45 o C were used in calculating the specific rate constants and were found to be 3.11 x10 -2 and 6.11 x 10 respectively. Furthermore, the values of the specific rate constants obtained were used in calculating the activation energy of the reaction (Ea) which was found to be 13.49075 kcal.","PeriodicalId":14488,"journal":{"name":"IOSR Journal of Applied Chemistry","volume":"32 1","pages":"91-94"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88128944","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The situation may worsen if immediate measures are not taken. Lead and cadmium are the main heavy metals in contaminated water and their harmful effects such as lung cancer, mental retardation and nerve disorder cannot be under estimated. Available methods for removing these metal ions from water such as use of activated carbon are very expensive and unaffordable to low income earners. Maize cobs which have minimal use after maize harvesting can be utilised to reduce environmental pollution. The primary aim of this study was to investigate the ability of maize cobs derived products to adsorb both lead (II) and cadmium (II) ions and remove methylene blue and turbidity from contaminated water. Maize cobs charcoal was prepared by heating dry maize cobs in a furnace in limited air. Activation was done by use of 1 M sulphuric acid and heating the mixture in a closed vessel. Maize cob ash was generated by heating dry maize cobs in a furnace. Ability of these adsorbents to adsorb lead (II) and cadmium (II) ions from the solution was investigated by carrying out batch experiment and varying parameters such as contact time, initial metal ion concentration, adsorbent dose, temperature and shaking speed. The data obtained was fitted in Langmuir and Freundlich models. Activated charcoal gave the best fit in Langmuir for lead ions with maximum adsorption capacity of 13.0 mg/g. Ash fitted in Freundlich model with r 2 =0.953. For removal of cadmium (II) ions, all the adsorbents gave best fit in Freundlich with maize cob charcoal having the highest adsorption capacity of 24.3 mg/g and r 2 =0.997. Among the three adsorbent only ash was found to have the ability of removing turbidity from water. This implies that maize cob derived products can be used to remove lead (II) and cadmium (II) ions","PeriodicalId":14488,"journal":{"name":"IOSR Journal of Applied Chemistry","volume":"71 1","pages":"58-68"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85507708","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The pest was first introduced in Tanzania in 2014.due to porous nature of our borders and lack of quarantine regulations implementation. Tomato producers in Tanzania have little understanding of leafminers, and hence lack best practices for it control. The pest have developed resistance to dozens of pesticides and therefore the (IPM) strategy that employs bio-chemical, biological, physical and cultural methods is the only best option we had at time. Since its introduction in 2014, there was no any sound action plan implemented. Thus, the aim of this review paper is to call for attentions and concerted actions of concerned sectors by describing the potential damage of the pest, its entry, pathways and its control methods. There is a need for all stakeholders to meet and discuss the possible ways of containing and controlling the current Tuta absoluta outbreak.","PeriodicalId":14488,"journal":{"name":"IOSR Journal of Applied Chemistry","volume":"9 1","pages":"14-22"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83568692","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
