Phosphorus umjikelezo

Phosphorus - omunye wemizila ebaluleke kakhulu izakhi zamakhemikhali ekusungulweni yezinto eziphilayo. He is ilungu protoplasm, futhi iningi izilwane nezitshalo amaprotheni. Man phosphorus kubalulekile ekuthuthukiseni lezitho nezicubu, kanye ukuqinisekisa ukusebenza evamile ubuchopho. Ayikho A. wonder Academician E. Fersman walibiza elementi Ukuphila nombono.

phosphorus umjikelezo ku uHlu Jikelele Lwamakheli yakhiwa amayunithi eziningana ezinkulu - ke rocks, inhlabathi, izitshalo nezilwane. Umthombo kakhulu phosphorus compounds e uhlobo apatite amaminerali, okubandakanya kusuka 5 kuya 36% i-nitrous phosphorous. Apatite zinhlayiya ezitholakala rocks igneous futhi ezindaweni bekanye sedimentary. izinqolobane enkulu yalesi amaminerali atholakala Brazil naseNorway, futhi emkhakheni omkhulu kunayo yoke Khibiny Mountains (Kola Peninsula).

Phakathi weathering ezenzeka ngaphansi kwethonya kwezimo asemkhathini, inhlabathi acid eziphilayo apatites ubhubhe zinengxenye kwamakhemikhali phosphorus umjikelezo esehlanganise bio-, hydro- futhi lithosphere.

Izitshalo ukuncela kusukela ziyoncibilika phosphate anions of wali band acid elementi buthelela ikakhulukazi ezithweni okuzala - izithelo nembewu. izingxenye ezahlukene zezitshalo esetshenziselwa izilwane ukudla futhi abantu, ne phosphorus umjikelezo uyaqhubeka.

Kunoma umzimba isilwane njalo ezenzeka izinqubo bokuphila elihlobene ne cleavage, zamagama kanye nezinye kugucuka chemical phosphorus compounds. Ngo ezincelisayo, lesi sici iqukethwe amaprotheni wegazi, ubisi, emsipheni, ethanjeni ubuchopho izicubu. Futhi ekhona ukubunjwa acid nucleic - zezakhi ehilelekile izinqubo sokudlulisela ukwaziswa kwezakhi zofuzo. Ngemva kokubhujiswa eziphilayo phosphorus umjikelezo avaliwe - element ebuyiselwa phakathi lithosphere, linyenti umjikelezo kwamakhemikhali. Ngaphansi kwezimo ezithile (isb, ushintsho abukhali izimo zezulu ngaphansi kunyakaza usawoti, izinga lokushisa, asidi emanzini nokunye.), IMisa ukufa eziphilayo kwenzeka futhi ekuqongeleleni izinsalela olwandle. Ngenxa yalokho, ukwakheka imali entsha yamadwala phosphorus-equkethe Lokudabuka sedimentary (isib, phosphate). Ngokuhamba kwesikhathi rocks organogenic - bioliths - baba umthombo omusha obalulekile walesi sakhi emjikelezweni biogenic.

Njengakuwo wonke umjikelezo we ndaba emvelweni, le nqubo ngamandla ungenela abantu. Phosphorus kanye compounds yayo asetshenziswa yokusansimbi, amakhemikhali umkhakha, ekwenzeni insipho, ukufana kanye imithi. Kodwa umthengi oyinhloko phosphate kuyinto ezolimo. Lo msuka kuyadingeka ukuze izitshalo ephezulu grade zom kanye fruiting, it kwandisa hardiness ebusika futhi ekusungulweni kohlelo impande. Kodwa nenhlabathi otshaliwe phosphorus ukunikezela kancane kancane mpilo, ngakho-ke kuyadingeka ukuba kwenziwe umquba ukwenziwa asebenzisa zonke okufanayo phosphate edwaleni apatite.

Ngakho, umjikelezo phosphorus kufakwe amasha izixhumanisi yabantu - umkhakha nezolimo. Izinto ezenziwa abantu okuhloswe ngazo okwandisa lokuhlushwa lesi sici ku imvelo. Lesi simo esiyingqayizivele sibangelwa, ngokuthi ososayensi sushi phosphatizing, kungenxa ukubamba kwasolwandle futhi isizinda phosphorus namaminerali ukusebenzisa amagatsha ezahlukene eyinkimbinkimbi Agro-ezimbonini. Phosphatization kakhulu uye wakwenza ngokuzimisela ukuthuthukisa ezifundeni anezimboni nge high ukwanda kwabantu. Ezindaweni ezigqagqene futhi apatite nezindawo izimayini phosphorite, kukhona, kunalokho, defosfatizatsiya.
