Labarai - Menene firikwensin motsi a cikin ruwa?

Haɓakawa shine ma'aunin nazari da aka yi amfani da shi sosai a cikin aikace-aikace daban-daban, gami da kimanta tsaftar ruwa, sa ido kan osmosis, ingantaccen tsarin tsaftacewa, sarrafa tsarin sinadarai, da sarrafa ruwan sharar masana'antu.

Na'urar firikwensin ɗawainiya don mahalli masu ruwa da tsaki shine na'urar lantarki da aka ƙera don auna ƙarfin wutar lantarki na ruwa.

A ka'ida, ruwa mai tsabta yana nuna rashin daidaituwar wutar lantarki. Rashin wutar lantarki na ruwa da farko ya dogara ne akan yawan abubuwan da aka narkar da su a cikinsa - wato, barbashi da aka caje kamar cations da anions. Wadannan ions sun samo asali daga tushe kamar gishiri na kowa (misali, sodium ions Na⁺ da chloride ions Cl⁻), ma'adanai (misali, calcium ions Ca²⁺ da magnesium ions Mg²⁺), acid, da tushe.

Ta hanyar auna ƙarfin lantarki, firikwensin yana ba da kimantawa kai tsaye na sigogi kamar jimillar narkar da daskararru (TDS), salinity, ko girman gurɓataccen ionic a cikin ruwa. Maɗaukakin halayen ɗabi'a suna nuna babban taro na narkar da ions kuma, saboda haka, rage tsaftar ruwa.

Ƙa'idar Aiki

Mahimmin ƙa'idar aiki na firikwensin motsi yana dogara ne akan Dokar Ohm.

Maɓallai maɓalli: Na'urori masu auna ƙarfin aiki yawanci suna amfani da ko dai biyu-electrode ko daidaitawar-electrode huɗu.
1. Aikace-aikacen wutar lantarki: Ana amfani da madaidaicin ƙarfin lantarki a kan na'urorin lantarki guda biyu (masu tuƙi).
2. Ƙaurawar Ion: Ƙarƙashin tasirin wutar lantarki, ions a cikin maganin suna ƙaura zuwa na'urorin lantarki na kishiyar caji, suna samar da wutar lantarki.
3. Ma'auni na yanzu: Sakamakon halin yanzu ana auna ta hanyar firikwensin.
