Potensi reduksi oksidasi (ORP) mengukur kemampuan danau atau sungai untuk membersihkan dirinya sendiri atau memecah produk limbah, seperti kontaminan dan tumbuhan dan hewan yang mati.<\/p>

Ketika nilai ORP tinggi, ada banyak oksigen yang ada di dalam air. Artinya bakteri pengurai jaringan mati dan kontaminan dapat bekerja lebih efisien.<\/p>

Secara umum, semakin tinggi nilai ORP, semakin sehat danau atau sungai tersebut.<\/p>

Namun, bahkan di danau dan sungai yang sehat, ada lebih sedikit oksigen (dan karena itu menurunkan nilai ORP) saat Anda mendekati sedimen dasar (lumpur; lihat gambar di bawah dasar danau).<\/p>

Ini karena ada banyak bakteri yang bekerja keras di sedimen untuk menguraikan jaringan mati, dan mereka menggunakan banyak oksigen yang tersedia.<\/p>

Faktanya, oksigen menghilang dengan sangat cepat di dasar lumpur (seringkali dalam satu atau dua sentimeter) dan ORP turun dengan cepat. ORP diukur selain oksigen terlarut karena ORP dapat memberi para ilmuwan informasi tambahan tentang kualitas air dan tingkat polusi, jika ada.<\/p>

Juga, ada elemen lain yang dapat berfungsi seperti oksigen (dalam hal kimia) dan berkontribusi pada peningkatan ORP.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Mengapa potensial oksidasi-reduksi penting?<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

ORP tergantung pada jumlah oksigen terlarut yang ada di dalam air, serta jumlah elemen lain yang berfungsi mirip dengan oksigen.<\/p>

Meskipun secara teknis tidak benar, oksigen dan elemen lain yang berkontribusi pada ORP tinggi secara efektif membantu 'memakan' hal-hal yang tidak kita inginkan di dalam air \u2013 seperti kontaminan dan jaringan mati.<\/p>

Ketika ORP rendah, oksigen terlarut rendah, toksisitas logam dan kontaminan tertentu dapat meningkat, dan ada banyak bahan mati dan membusuk di dalam air yang tidak dapat dibersihkan atau terurai.<\/p>

Ini bukan lingkungan yang sehat untuk ikan atau serangga.<\/p>

Di perairan yang sehat, ORP harus terbaca tinggi antara 300 dan 500 milivolt.<\/p>

Di Utara, kita mungkin mengharapkan ORP rendah di perairan yang menerima masukan limbah atau limbah industri.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

ORP diukur langsung di air danau atau sungai yang Anda selidiki menggunakan sensor ORP.<\/p>

ORP diukur dalam milivolt (mV) dan semakin banyak oksigen yang ada di dalam air, semakin tinggi pembacaan ORP.<\/p>

ORP bisa di atas nol atau di bawah nol.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Oxidation-Reduction Potential (ORP) What is oxidation-reduction potential? Oxidation-reduction potential (ORP) measures the ability of a lake or river to cleanse itself or break down waste products, such as contaminants and dead plants and animals. When the ORP value is high, there is lots of oxygen present in the water. This means that bacteria that decompose dead tissue and contaminants can work more efficiently. In general, the higher the ORP value, the healthier the lake or river is. However, even in healthy lakes and rivers, there is less oxygen (and therefore lower ORP values) as you get closer to the bottom sediments (mud; see the picture below of a lake bottom). This is because there are many bacteria working hard in the sediments to decompose dead tissue, and they use up a lot of the available oxygen. In fact, oxygen disappears very quickly in the bottom mud (often within a centimeter or two) and ORP falls quickly. ORP is measured in addition to dissolved oxygen because ORP can provide scientists with additional information of the water quality and degree of pollution, if present. Also, there are other elements that can function like oxygen (in terms of chemistry) and contribute to increased ORP. Why does oxidation-reduction potential matter? ORP depends on the amount of dissolved oxygen that is in the water, as well as the number of other elements that function similarly to oxygen. Though not technically correct, oxygen and other elements that contribute to high ORP effectively help \u2018eat\u2019 things that we don\u2019t want in the water \u2013 such as contaminants and dead tissues. When ORP is low, dissolved oxygen is low, the toxicity of certain metals and contaminants can increase, and there is lots of dead and decaying material in the water that cannot be cleared or decomposed. This is not a healthy environment for fish or bugs. In healthy waters, ORP should read high between 300 and 500 millivolts. In the North, we might expect low ORP in waters that receive sewage inputs or industrial waste. [Oxidants = Damaging Cells] [Antioxdidants = Protecting Cells] How do we measure oxidation-reduction potential? ORP is measured directly in the lake or river water that you are investigating using an ORP sensor. ORP is measured in millivolts (mV) and the more oxygen that is present in the water, the higher the ORP reading is. ORP can either be above zero or below zero.
