Kajian kesan adid terhadap bahan logam-kes plat aluminium

Kajian kesan adid terhadap bahan logam-kes plat aluminium / Darol Shafek Yusof
Pencemaran udara yang semakin meningkat di negara ini mengakibatkan kesan yang pelbagai keatas setiap objek di muka bumi, bukan sahaja ke atas hidupan malah ke atas bangunan. Oleh yang demikian bandar yang pesat membangun seperti Seberang Perai merupakan salah satu lokasi yang pelbagai aktiviti yang menyumbang kearah pencemaran. Tidak dapat dinafikan pelbagai aktiviti yang berlaku dalam urbanisasi suatu bandar bukan sahaja manusia malah ia urbanisasi ini melibatkan hidupan persekitaran lain. Pelbagai jenis hidupan akan bertambah mendiami kawasan urbanisasi sama ada secara semulajadi dan bukan semula jadi. Tetapi aktiviti manusia mengakibatbatkan pencemaran dan semua hidupan terpaksa menerima akibat yang sama contohnya hujan asid. Kajian ini dijalankan ke atas plat logam aluminuim untuk mengetahui kesannya oleh pH hujan asid. Aluminum merupakan logam nipis yang terhakis dengan kadar yang rendah berbanding logam-logam lain apabila terdedah . Melalui keputusan ini juga kesannya terhadap hidupan lain dapat disedari. Sekiranya aluminium terhakis apabila terdedah kepada hujan asid apatah lagi hidupan lain yang terdiri daripada sel-sel hidup. Perubahan kimia berlaku dengan cepat berbanding perubahan fizikal. Pendedahan keputusan kajian ini kepada pihak berkuasa akan lebih mendorong mereka bertindak mengawal kualiti alam sekitar. _______________________________________________________________________________________________________ The increase of air pollution in urban area in Malaysia gives many effects to all objects and lives. So, Seberang Prai is the best location to study in air pollution because in that location the urbanization process so fast. Many activities in Seberang Prai that give negative effect to the air. The urbanization process involving and effecting to another species and environment. Every species will go to the urban areas to survive because there are many resource for survive their live. But the activities from human make the environment become pollute and effecting the acid rain. Acid rain has a variety of effects, including damage to forests and soils, fish and other living things, materials, and human health. In this study, the main focus is effects of acid from the acid rain to the aluminum plate. As we know the aluminum is most thin metal but the corrosion attack is lower than other metals exposed. Also from the result we can know the effect to other living cells if the corrosion happened to the aluminum. Chemical reaction process is faster than physical process due to time. Government should take some possible steps to control the air quality when they exposed about the results.
