4.2.1 Effects of Initial dosage on Lead Adsorption
This experiments were carried out to investigate the potential of banana peel as adsorbent for the removal of heavy metal. For this experiment, the bisorbent is untreated and less remove of heavy metal than treated biosorbent.
As can be seen from the result, at mass of 0.4g, the percent of removal was 37.38% and it gradually increase to 49.30% at 2.4g.From the result, it can be seen that the high dosage of absorbent, it more good removal absorbent to the lead. The effect of dosage show that when higher amount of banana peel are used, percentage of removal(lead) will increase.
But, the dosage of adsorbent on 0.8g and 2.8g, its have the negative on the conentration of lead. Its because the solution has contiminated. Besides that, the solution also was stirred maximully and not regularly. This results doesn’t counted in the graph and maybe should redo the experiment with carefully.
Results showed that the adsorption efficiency is highly dependent on quanttity of adsorbent added. This was expectedas with increasing conc...

- The effect of initial pH on dyes adsorption using three different types of granular iron oxide was evaluated within the pH range of 2 until 8. For this analysis, only Methylene Blue and Orange II Sodium Salt were analysed. Alizarin Red S is not suitable for this analysis as it is very sensitive to acid and base. It will change colour to yellow when it is in acid form and red when it is in base form. This is the reason it is used for pH indicator in many applications. For MB, as can be seen from the result in Figure 3.5, at pH value of 2, the percent of removal is 0.00% and it gradually increase to 3.86% at pH of 4, 12.73% at pH of 6 and 14.37% at pH of 8 for adsorption by untreated granular...

- John Soluri’s book, Banana Cultures, examines the production of bananas in the world market, “interactions among diverse and often divided people, not-so-diverse banana plants, and persistent yet unpredictable pathogen’s that formed and reformed tropical landscapes and livelihoods in export banana zones” (Soluri 5). Soluri talks about the historical entanglement of the Panama and Sigatoka pathogens and the export of bananas cultivation through agro-ecology. While the fungal pathogens infected Latin America, the Gros Michel banana invaded the United States.... [tags: Banana, United Fruit Company, Cavendish banana]

- The Role of Consumers in Relation to Cod and Bananas Bananas and Cod, two foods that aren 't paired on many plates, but certainly share similar stories with regards to their harvesting. The fishing industry has recently come under fire again due to the improper methods used to obtain fish in mass. This is due to the consumers demand for an easily recognizable type of fish. Bananas have fallen into a similar issue, in which nearly every store only wants the one type known as, the Cavendish. Other types that vary in size or appearance are exceptionally less valuable from a sellers perspective because of the public demand for the current product....

- Banana or Musa acuminata, is one of the most vital staple crop in the tropical areas. It is a common food to every person especially in the Southeast Asia where there are many banana plantations like here in the Philippines. Bananas naturally grow in shady and moist regions like on marshlands and other wetlands. The plant of this fruit usually reach a peak height of 20-25 ft., bearing up to 200 number of bananas divided into clusters commonly called the “hands”. Each banana has a size of up to 12 inches in length and 2 inches in width.... [tags: philippines, banana peels,musa acuminata]

- Up until the age of thirteen, shopping always been torture. Shopping was so bad that I would never buy anything for myself. When I would wear anything other than athletic shorts and a t-shirt, I would have to raid my older sisters’ wardrobe- who just happened to be my size. After losing about twenty pounds in eighth grade, I started to love shopping- much to my parents’ dismay. While trying to find my own personal style, I began to shop at stores similar to Banana Republic and Gap. It soon occurred to me that, although they bear some minor similarities, the difference between Banana Republic and Gap are pronounced.... [tags: Banana, United Fruit Company, Banana republic]

- Key Question) – How does the global trade in bananas reflect injustice in free trade arrangements. “Although bananas may only look like a fruit, they represent a wide variety of environmental, economic, social and political problems. The banana trade symbolises economic imperialism, injustices in the global trade market, and the globalisation of the agricultural economy. Bananas are also number four on the list of staple crops in the world and one of the biggest profit makers in supermarkets, making them critical for economic and global food security....

- Sir Robert Peel’s Principles of Policing According to the New York Times, Sir Robert Peals had nine principles of policing. The first one states, “The basic mission for which the police exist is to prevent crime and disorder.” The next principle says “the ability of the police to perform their duties is dependent upon public approval of police actions.” The third principle is “police must secure the willing cooperation of the public in voluntary observance of the law to be able to secure and maintain the respect of the public.” Principle number four “the degree of cooperation of the public that can be secured diminishes proportionately to the necessity of the use of physical force.” Number f...

- Police departments in the United States and over the world have been applying Sir Robert Peel 's twelve principles of policing for beyond a century. There have been almost no alterations administered since the policies were executed in England 's "Scotland Yard." Numerous of these principals are behind today 's investigating and policing practices. (1) THE POLICE MUST BE STABLE, EFFICIENT, AND ORGANIZED ALONG MILITARY LINES. A police department must be able to stand the test of time. By this I mean, they must be capable of continuing developments in government and be able to respond to whatever situation they may confront.... [tags: Police, Crime, Constable, Robert Peel]
