چکیده

نیکل یکی از ناخاصی­های فلزی می­باشد که قبل از الکترووینینگ روی باید از محلول الکترولیت حذف شود. در این پژوهش پارامترهای موثر بر فرایند حذف نیکل در کارخانه روی دندی توسط روش سطح پاسخ مورد بررسی قرار گرفت. نتایج آزمایشات نشان داد که بهینه­ترین حالت برای حذف نیکل در دمای 85 درجه­سانتی­گراد، زمان ماند 60 دقیقه، 2.5 گرم بر لیتر غلظت پودر روی، اختلاط 500 دور بر دقیقه و pH برابر 5 حاصل شد. با توجه با مدل حاصله از نرم افزار دیزاین اکسپرت، بیشترین تاثیر گذاری به ترتیب متعلق به غلظت، زمان ماند و دما می­باشد.
